I think this could be easily done with presence priorities when
application is implemented as client. Each application instance would
log in to the same Jabber account, but with different resource. And they
would change their presence prioties according to their current
resources and load. The Jabber server would send messages always to the
instance with highest priority. This is simple and not perfect load
balancing solution, but may be good enough in many cases.

Other solution would be to make some kind of message multiplexer - it
could be a component or a client.
