If you want to set up a SOAP web service in Python and don't want to use a monster server like twisted, but instead prefer a small, lean web server based on Medusa (though with dynamic multithreading!), you can check out my linked project. Nothing groundbreaking, but quite useful as an all-rounder. UPDATE: the stable version is now 0.2.0 and includes XML-RPC support in addition to SOAP. Version 0.3.0 is now in CVS, which adds support for implementing REST APIs.
