The xmlrpclib module predates SimpleXMLRPCServer by a fair amount. The
getStateName() test was meant to connect to UserLand's original test server.
As I recall, that was the sole function it exported. I don't see any reason
why SimpleXMLRPCServer needs to implement getStateName(), but I imagine it
would be reasonable for xmlrpclib's test to call pow().

You should be able to build a server and a client with just the standard
Python distribution. If performance is an issue (it will be if you are
passing large chunks of data back and forth), there are some things you can
do to speed it up:
* Install Fredrik Lundh's sgmlop module.
* Marshal or pickle your data first, then base64 encode them before
passing them to or fro. This greatly reduces the number of XML tags
on-the-wire, and thus the encode/decode time and data size.
Obviously, this only works if you are talking Python-to-Python.
* Tweak things to gzip-encode the traffic between server and client.
* Use the xmlrpclib.MultiCall class to bundle logical multiple calls
into a single physical XML-RPC call.
