LLuna - the Jabber Virtual Presence Project
I ran across an interesting Jabber application today called Lluna. There’s also a firefox plugin for it. The concept is pretty simple, it uses jabber for communication, and tracks what website you are currently viewing. It throws up your avatar at the bottom on the web browser for that page, as well as the avatars of other users currently at the site. This could, for instance, let users at a blog community like brendoman.com chat in real time about the news on the site.
