Putting the python scripts up is no problem; I'll push them somewhere (like github), and people can take them and run with them.

There are practical problems with "putting them on the website", since they need regression logs to work from, and those are fairly large.
[ My trunk runner (6 configs) is about 300 MB/day ]

If anyone has ideas on how to deploy this, I'll be happy to work with them.
