The current xmlrpclib can't communicate through a proxy
server.   In particular, the two Transport classes
contained within xmlrpclib use httplib directly and, as
such, do not support the proxy handling as offered by
urllib.

Or so it seems.

I'm in dire need of support for proxies in xmlrpclib
and will be investigating creating a custom Transport
class that uses urllib as opposed to httplib to gain
support for proxies.

Assuming success, I'll post the new transport class
here.   In the interim, I figured I would log a bug in
case anyone else is interested in working on the
problem (or already has a solution :).
