[mod_python] Open source projects based on mod_python

Hello,

I am trying to master mod_python and after reading its documentation,
running the samples from it and lurking in the mod_python mailing list
I would like to know some nice open source projects that use
mod_python. I am particularly interested in how people deploy their
projects to Apache Httpd and how the handlers are used in the real
world.

Thank you in advance for your pointers.

Regards
Rambius
