Something like asynchronous XML-RPC possible?

Thank you and Laura and others for your comments and all.  Ammunition
for my next meeting :)

I can think of one argument they will confront me with I do not have a
good answer for.  It is the "blocking caller" or "inefficient thread
creation" thing.   As Stuart guessed, the application is indeed sort
of realtime, they want the caller to continue processing *immediately*
after sending the event to the server.  The prototype I have now does
send an event by means of an XML-RPC call in a separately created
thread (just using pythons' nice ``thread.start_new()``) because it
*has* to receive a return value from the server even though it will
never look at it.  If they say that creating a thread for this is
highly inefficient and a wrong design, what should my answer be?

Stuarts' "industry standard" arguments are very nice, I expect they
will help a lot in deciding in favor of TCP and XML-RPC and HTTP(S)
and "doing what everybody does", which would be much easier for me :)
