I've tenatively repackaged the WSGI servers, middleware, and publisher into the "flup" package (named after the project that spawned all these modules). For now, you can get it from the SVN repo at <http://svn.saddi.com/flup/trunk>.
Pros: allows me to refactor (especially the servers). There are 3 types of servers (fcgi, ajp, scgi) with 2 flavors of each (threaded, forking). Better organized, easier to maintain.
Cons: No more single-module servers or publisher. No more picking and choosing modules. You have to grab the whole package (because of the refactoring).
