It seems that Facebook have just opened up their XMPP server for 
Facebook Chat.


The server is at chat.facebook.com:5222 (sans SRV records) and the only 
stream features advertised are DIGEST-MD5 or "X-FACEBOOK-PLATFORM" 
authentication.  There's no TLS, no compression, and possibly no access 
to people who don't have a Facebook username (i.e. those who only have a 
user ID).

The basics are supposedly all there: rosters, presence, plain text 
messaging, vCards.  I could only get a 503 error so far when trying to 
authenticate, so can't comment any further..
