PeerKat

A BlogWeb RSS aggregator that runs as a Web Server on your desktop. Built in Python.

Last time I tried it, it didn't work well with many (all?) Manila Userland-based WebLog sites. I couldn't figure out whether it was because it wanted only RSS 1.0, or if there was another problem.

I wonder how much it would take to hack this into a Zope product?
