Ken MacLeod has started implementing SOAP in Perl and in Python. An online demonstration server for the Perl implementation is available.

MacLeod bills both implementations as "minimal" currently, but some useful functionality is available. The Perl version, SOAP-RPC, has a demo server at http://Casbah.org:8000/ and also a command line program for exercising SOAP methods.

The Python implementation supports the SOAP "Section 8" serialization format, aping Python's "pickle" API. It is available by anonymous CVS from:
