[jdev] best way to connect 2 servers

[Sascha]

hi this is may a stupid question, but what would be the best way you 
think to connect
a NON Jabber with a Jabber server,
the goal would be to have interconectivity message exchange maybe also
whiteboarding dident checked the JEPs for that now, the other server has no
message protocoll or better it provides raw data access from the client,

what i know whant is
1. use the other server for communication aswell as the jabber server 
for connection to jabber clients
should be something like a proxy.

so what way would you choose , would you may implement server2server 
xmpp on the other server?

are there any other ways?
