RPC client class?

[Dick Watson]

We have a legacy device that exposes an RPC server. We have an RPCL 
defininition of its interface. We want to develop an RPC client of this 
interface in Python that will be usable in both Win32 and open systems 
environments.

I can find some *very* dated references to a demo/rpc.py, but I can't find 
such a file on my Win Python install. There is an rpc.py in idle, but it 
doesn't seem to be a general purpose implementation. (I can find **lots** of 
references to xmlrpc.py, but the server predates all of this neato XML 
stuff. I also found the "Stackless" rpc.py; it wants to modify base Python. 
I'd rather not diverge from the stock Python.)

Is there a Python module suitable for RPC client creation? Where? Why is 
this not a standard class? Are we nuts to pursue this course?
