By using something like a nameserver. A machine that keeps track of who's online on
which machine. Basically, the nameserver would deal with the registration of users
and  assign them to a server, e.g. foo at jabber.com becomes foo at jabber2.com. If
someone sends a message to foo at jabber.com the receiving server first does a look up
to see wheter this user is registered with the name server and if he/she is, forward
the message to right server. Of course, that would change the whole rooster-scheme.
What do you think?
