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..

There were lots of things that just didn't work -- like sending IQs between clients other than namespaces that the server knew about. I'm sure we'll start to see things shape up over time. Works great for me [shortname]@<a href="http://chat.facebook.com">chat.facebook.com</a> FTW. I'm not going to hold my breath for federation, but who knows? Would be cool, but would totally break their friend/chat paradigm. -Fritzy
