An alpha of SamePlace is online at http://www.sameplace.cc/alpha.
SamePlace is a Jabber client for Firefox. Besides normal operation, it allows the user to "enter" any web page as if it were a room, and chat with other visitors. SamePlace relies on the jsjab javascript library for Mozilla, which allows connecting to a jabber server in the usual (i.e. non-HTTP) way. Comments and bug reports are welcome. Enjoy, Massimiliano
