A question for people who know Perl and Python

[Dave Winer]

Suppose for the sake of argument, there were no XML-RPC (or SOAP).

Let's say I have a project and a member of the team works in Perl and has a
component that does something I need that's not trivial, it's deployed and
debugged, it scales; in other words, there no good reason to re-implement it
in another language.

Now assume I'm doing the user interface for this application in another
language, say Python, running on another machine. Further, assume it's a
good candidate for HTTP-based integration -- the messages that pass betw my
user interface written in Python and the Perl app would be one or two every
hour.

Now here's the question. What libraries would I use in both Perl and Python
to do this integration? What would the code look like? In other words, does
XML-RPC offer a new feature to Perl and Python programmers?
