It is not clear from whom he is requesting such action, though.

I think the OP is indeed requesting only the first
half. SimpleXMLRPCServer.py is part of the standard library in current
releases, and the standard library *only* works with the Python
interpreter that ships with it, not with earlier versions, not with
later versions.
