Google Talk now talks to other Jabber servers!

Well it appears that Google has finally let their Jabber server talk to other XMPP messaging systems, meaning that if you use Jabber somewhere then you should be able to now communicate with Google Talk people (including VOIP if your client supports it thanks to Google releasing their Jingle specs openly as well as a sample library) as well as with anyone else on a Jabber server.
Nice one Google!
