There used to be a page on the wiki of case studies, but I couldn't
find it. But one C-specific case study is the port of Wing's extension
modules to support from Python 2.0 to 3.0:
http://pythonology.blogspot.com/2009/02/making-code-run-on-python-20-through-30.html
. There is also a wiki pages explicitly about porting C code:
http://wiki.python.org/moin/cporting and
http://wiki.python.org/moin/Py3kExtensionModules . Those latter pages
include links to the official porting docs:
http://docs.python.org/3.1/howto/cporting.html .

And as Georg pointed out there is always the python-porting mailing
list: http://mail.python.org/mailman/listinfo/python-porting .

I'm afraid there is some FUD going around here, which is
understandable since no one wants to burn a ton of time on something
that will be difficult or take a lot of time. But I have not heard
anyone in this email thread (or anywhere for that matter) say that
they tried a port in earnest and it turned out to be difficult.
