Perhaps we should start a small project for such a tool written in
Python (to bring the subject back on topic ;-) and place it on
the web somewhere ?!

If we separate out the engine from the rest we could also have
different backends, e.g. one which hooks into .forward as filter,
a daemon style backend which does on-server flagging based on
imap, a Mailman filter backend which does the same for mailing
lists etc.

Would be cool to have python-list mark non-python spam using a 
special header automagically ;-)
