Something like asynchronous XML-RPC possible?

Are you tied to XML-RPC? Is UDP a requirement?
If not: Pyro supports your desired usage pattern already.
Either use Pyro's asynchronous Event Server, or use Pyro's
"oneway" method calls.
They currently use TCP for reliable delivery, but once the
request has been sent, your program carries on, not waiting for
any answers from the other object.
