Facebook Chat’s integration with AOL’s AIM was not a one off event, rather a part of something bigger. As of today, Facebook Chat is now available “everywhere” (including desktop apps). In order to accomplish that Facebook has implemented the Jabber XMPP protocol, which is an open messaging protocol that is supported by most instant messaging softwares, including iChat, Pidgin, Adium, Miranda – and yes Google Talk also supports the same Jabber XMPP protocol.
