In Yahoo, I have looked at having multiple clients be presented with the 
Yahoo presence information synchronously. To say the least, it is not a 
trivial fix. The Yahoo transport has a one-to-one relationship between a 
Jabber client (and it's resource) and the Yahoo session.

Not that I know of ...

This is going to be problematic, as Jabber allows for multiple 
connections using the same JID, but none of the other services (Yahoo, 
AIM, etc.) do. To keep all the clients using one JID in sync with each 
other for presence and roster changes would require a substantial change 
to how all the transport are currently coded.
