Livejournal does XMPP/Jabber

Wow, livejournal now does xmpp/jabber. Which means that my gmail self can talk to my livejournal self. Very cool. I looked at doing some integration at work, using xmpp to notify me when events happened (like a referral was entered, an error happened, etc..) but couldn't find any good .net-based libraries. I may have to look again.
