A virtual presence client needs information to display people who meet. It needs
a name, an image, maybe an animated avatar, and more. This document describes
the storage and exchange of public user identity data. The virtual presence
identity data format is optimized for VP applications, where many people need
the publich data of their peers, some only once, some repeatedly, where changes
happen frequently and must be propagated quickly with minimum bandwidth.
VPTN-3: User Data
nloose liveblog: Meet different people who are surfing the same websites as you
at the same time.
nloose is a browser plugin that shows people who are surfing the same web site
at the same time. It shows an indication that other users are avalable and a
chat window with images.
nloose installs a browser toolbar. It is available for IE and Firefox, which is
remarkable. But the software seems to be spanish only currently. I installed,
and did not see anyone, but that's probably just a matter of time.
The document describes the location mapping for virtual presence.
VP takes place on web pages. VP uses the content of the web. If users navigate
to the same page, then VP will make them aware of each other. This is a high
level view. Technically, they both join the same chat room and the chat server
tells them about each other.
Location mapping is the key component, that lets users join the same chat room
when they navigate to the same URL. The location mapping process associates a
chat room with the document URL. It maps the document URL to a chat room
Mozilla Labs has cooked up some ideas for a new way of sharing information on
the web: through your Firefox Browser. The Coop is a project to experiment to
turn your Firefox browser into a social network.
Me.dium, the browser add-on tool that is aiming for more social web browsing,
has added its service to be available for Internet Explorer users. Previously
only able to be used by Firefox and Flock users, Me.dium can now reach a much
News on Mashable
Me.dium announced it had raised $15 million in a second round of funding,
bringing its total amount of capital to $20 million from Commonwealth Capital
Ventures, Spark Capital, Appian Ventures, Brad Feld, and Elon Musk.
This makes Me.dium the front running company in the emerging Virtual Presence
field. When they closed the deal they had 20.000 registered users. They won't
tell how many active users. Could easily mean $ 10.000 investment per active
user. Obviously someone expects whole lot more users, features and services in
the Co-Browsing/Virtual Presence field.
Zweitgeist ended their beta, renamed and rebranded their product to Weblin, and
launched on a new server cluster.
Your zweitgeist is now a weblin. They renamed to weblin, because weblin is
better suited for international expansion. The site also got a new green design
and a new expressive logo. There are still 2 avatars on a browser window. But
the new logo shows how they emerge from the window supporting the claim: free
Zweitgeist set up a new server cluster with redundancy on all components and
enough processing power for 20.000 concurrent users. Easily expandable to
100.000. That's already in the Second Life dimension and should be enough for a

Nice implementation. It is built on prototype.js (AJAX) and uses a cool JS
window class (prototype window) to show a chat like window on top of the normal
Seems to be a small shop, but technically well done. Not that small projects
have a problem with that. Small projects are usually driven by a single very
good coder. I am definitely in the small shop corner. But there are many people
who expect professional work only from big companies.

Me.dium, a new browser plug-in that enables XMPP-based social browsing and
messaging with other users of the World Wide Web, has opened up its private beta
to members of the Jabber community.

It's a (yet) Firefox extension which shows your virtual neighbors in a sidebar.
Protocol seems to be XMPP over HTTPS (@me.dium: correct?). Looks quite
professional, smooth animations, additional features, cross web-site chat, no
integration with Jabber roster (but hey, you'll want that because they mention
Jabber. If they had a proprietary protocol, then you would not even think about
roster integration). Well done.
My #6 in the list of firefox-extensions-for-chat-on-web-pages. But surely one
of the best in this category.
Zweitgeist, the LLuna 2 successor entered the Open Beta phase today. Here is
german press release.
Zweitgeist is the continuation of the LLuna research projects. The zweitgeist
team created a web portal, added animated avatars and runs its own XMPP servers
for all zweitgeist users.

The JEP Editor has published a proposal for a new JEP. Title: User Browsing
Abstract: This document defines an XMPP protocol extension for communicating
information about the web pages a user visits.
The new draft is complementary to JEP-0151 (http://www.jabber.org/jeps/jep-0151.html).
While "User Browsing" sends URLs to
subscribers, "Virtual Presence" joins chat rooms while browsing. "User
Browsing" is aimed at telling people you already know about your browsing
"Virtual Presence" on the other hand, connects people you don't know in
advance. So, "User
Browsing" means co-browsing with friends, "Virtual Presence" meeting with
Itzl shows users as small figures on the page. They can walk around and have
chat balloons above their head. The system has the usual chat input, emote,
popular sites, profile, etc. features. It looks very complete. It is also very
pretty and looks professional.
Itzl is one of the prefix-your-URL-and-get-an-IFRAME systems. This makes it #3.
Currently Firefox only. I suppose they use XPCOM objects for their
communication. This will have to be ported to XMLHTTPRequest on IE or
re-implemented as an IE browser extension.
Update: A quick Ethereal shows, that the protocol is HTTP based (who would have
assumed otherwise). So, porting communication to IE should be easy. I still
wonder what FF features they need.

'Skype Me': EBay to Add Button to Listings
Ebay finally integrates Skype into its core business by enabling direct calls
between buyers and sellers. The virtual presence related news is, that buyers
will see when sellers are online. So, Ebay jumps onto the virtual presence train
without knowing yet.
Microsoft joins the chat-on-web-pages-sidebar game with their new Community
Bar. I doubt, that this is the first such sidebar for IE, but it is the first
the general public learned about. The Community Bar can also display notes of
other users, take tags, and show backlinks to the page.
We welcome Peekko Chat in the community of
firefox-extensions-for-chat-on-web-pages. Peekko Chat is #5 on this list. Tell
me, if you know others, not listed here.
Peekko Chat is a new Firefox extension that makes every web page a place where
people can congregate. It adds a toolbar to Firefox that shows how many people
are in that page's chat room and allows you to instantly connect with them.
The Web site www.webmobs.de published a manifesto which enumerates virtual
presence issues, problems, solutions and rules of conduct. It is a collection of
rules for life on the Web. Besides many other topics, the manifesto introduces
the notion of responsibility for public Web infrastructure and domestic
authority on Web space.
Another Firefox extension, which creates a sidebar with a chat channel for Web
pages. That makes it about #4:
"Surfing the web is like travelling alone. You get to see beautiful places,
funny places, interesting places, yet they all have one bad thing in common:
Of course it only seems so. There's people visiting the same place you're
visiting: reading your blog, listening to music you like, checking out the same
movie, the same book.
Wouldn't it be nice if they were just a click away?
Now they are."
