SourceForge.net: Project Info - Fast Python Xmlrpc Library

SourceForge.net: Project Info - Fast Python Xmlrpc Library: "An extremely fast implementation of the xmlrpc spec for Python (written in C). It supports both blocking and non-blocking clients and servers on Windows and POSIX platforms. Version 0.8.1 is 100% compliant with the www.xmlrpc.com validator."

Also, it features an xmlrpclib compatability file :)) but there is no binary available for python 2.3(.5)... So will have to compile either yourself, or ask someone else...
