This morning, I am playing with both Medusa and Twisted.  Both are Python frameworks for writing socket-based servers (i.e. HTTP, FTP, etc.).  Zope was based on Medusa, but there was talk about replacing Medusa with Twisted.  I like Medusa because its straight forward.  I was up and serving web pages in 10 minutes with Medusa.  Twisted is, well, twisted and harder to figure out.  I'll bang on it for the rest of the afternoon.  Stackless Python looks interesting and useful for running large population of desktop agents, but I don't have time to examine it in detail.  Problem with all these crazy Python projects are that documentation is generally poor and one has to resort to Googling web sites and newsgroups.  I am starting to miss Java already...
