Something like asynchronous XML-RPC possible?

Interesting. Not to show off, but for comparison, I just did a quick 
test with Pyro.
On my measly 128kbit internet uplink, it reaches:
  avg. time per method call: 0.04039
On my 100 mbit LAN, it reaches:
  avg. time per method call: 0.00147

Pyro's oneway call (asynchronous) is *much* faster than that:
100 times fe 0.333815932274 ( that's 0.0033 sec/call) on my internet 
link, and 100 times fe 0.0474219322205 ( so that's 0.00047 sec/call) on 
my LAN.

Notice how much faster a oneway call really is: 12 times faster on my 
slow uplink, but still 3 times faster on the fast network.
