I have chat build on strophe. When I try to invite my facebook xmpp username I got this on my server:
Trying to open s2s connection: pregmatch.org -> chat.facebook.com with TLS=true
s2s connection: pregmatch.org -> chat.facebook.com (remote server not found)
Reconnect delay expired: Will now retry to connect to chat.facebook.com when needed.
If facebook support xmpp, this is stupid if you can not invite some user, or they can not invite you (no metter if you have facebook account or not)?
In XMPP world, apart from client-server architecture upon which Jabber/XMPP communication is based there is another aspect called “federation”, i.e., the ability for two XMPP servers in different domains to exchange XML stanzas. Unfortunately facebook doesn’t support federation. Google Talk servers do. As of result you won’t be able to add or interact with facebook jabber id’s
