Facebook enabled their XMPP support today. And unlike AIM, I think it’s here to stay!
How do I log in?
Well, just use your Facebook Username and Password, and use the server chat.facebook.com.
So, what does it do?
Well, so far as I can see, it only does Chat. I heard from some people that vCards work, but I cannot confirm this. Service Discovery / Disco is also currently not available. The resource name is your pre-defined one in lower case, followed by a long hash (probably cluster routing information), here my example for Homer-LAN: homer-lan_5769bd69_47F44ABA3F597
I am sure that more and more functions will become available over the course of the next few months. It’s just a matter of slowly scaling it.
One thing which would also be cool is S2S connectivity.
But we’ll see how it goes.
