Integrating PHP & Python through a light-weight rpc mechanism?

I doinked around with an RPC protocol based on XMLRPC awhile ago which used
the pickle binary format as the serialization mechanism instead of XML.  You
could try something like that.  You're welcome to the code.  You'll probably
be exchanging basic data types (that is, not class instances), so marshal
might also be an option, and you'd have the benefit that you could adapt the
existing marshal module's code for PHP.
