without examples of mud_name and player_name, I'd suggest making the 
domain identify the mud via dns. You do get to route to a component by 
the full domain ; you could have a jid of player_name at mud-name.server 
(where player_name and mud-name abide by the character requirements of 
the respective parts of the jid).

Assuming you are hoping to reuse the existing open-source 'jabberd' 
implementation, I'd mention the option of connecting as a component - 
its not xmpp-core per-se, but it does let you route all traffic to a 
particular domain received by jabberd to a particular piece of software 
over one socket. You run mud-name.server as a part of your mud as a 
component, and get a inbound flow of remote->s2s->component->mud->player.

It might also be possible to use an external s2s program (I believe 
there are two now) which acts as a component; a little off the beaten 
path but requires fewer moving parts. One jabber-server connection can 
transport data for many users.
