Google Talk and XMPP
Gary Burd of Google announced today at the Talkabout blog that Google Talk is now federated with the world-wide XMPP public network [pointer from Om Malik]
[from Google Talkabout: XMPP Federation]
I flipped the switch to connect the Google Talk Service to the public XMPP network this morning. Google Talk users can now chat with users on other XMPP services and vice versa.
I asked Peter Saint-Andre of the Jabber Foundation what this means:
It means that Google Talk is now yet another server on the Jabber network. In plain English: you can now chat with your Google Talk friends from your account on any other Jabber server. The kind of open communication we've had in the email world since 1993 or so, except without the spam.
I am still awaiting the interoperability of Gizmo with Google Talk, which has been supposedly in the works for a long time.

The Gizmo project has had Jabber support since v1.1, now that Google have flipped the switch, you can IM between the two today.

About Gizmo, it has been using an open (to the public jabber network) Jabber server for presence and IM for several months. Therefore, there is no reason why IM and presence should not work between Google Talk and Gizmo.
As voice is concerned however, they are not compatible as Gizmo uses SIP and Google Talk uses Jingle (based on XMPP). Maybe that is what you were talking about
