Google opens up their Talk servers

After long anticipation in the Jabber community Google have finally turned on server-to-server communication (Usually known as s2s). This means that users on servers other than the Google Talk server can now excange messages with each other.

Official Google Talk blog: XMPP Federation (a technical term for s2s ;))

Some Jabber clients are also working on support for Jingle, the standard that the Google Talk client uses for audio (soon video).

Some Jabber servers are showing problems with s2s communication with the GT server, apparably those running jabberd 1.4 (not the CVS version that jabber.org uses). ejabberd works fine.

--Added--
It also seems that MUC support is patchy, but possible (not in official client of course). Again it depends on the server.
