Why not add authentication and message relaying to the S2S protocol.

This would give four advantages;

1. Any user could log into any machine and the server would relay the
authentication request to the relevant machine to handle authentication.

2. The messages for that user would be relayed to the server they are
logged in to and then forwarded on to them.

3. Clusters or farms could be constructed to server a a single jabber
community and the load shared between them.

4. This would only involve a change to the S2S protol and servers
supporting it (of which there are few), and would leave the C2S protocol
unchanged and thus not require any client changes.
