Matej and I have been working on this little project of and on for a
little while. I plan to make the code available at
http://starship.python.net/~tbryan/ as soon as I've degugged some stuff
that I was adding this weekend.

I don't use NT, but I have one suggestion.
Aren't filenames case-sensitive on NT? Look at your traceback. Notice
that the error is actually coming from a call to os.stat() inside of
os.path.samefile(). The error says that there is "no such file." I think
that's because you're calling string.lower() on the filenames before
calling os.path.samefile(). If you have a file called MatejsFile,
string.lower() turns it into matejsfile...which may or may not exist.
When it does exist, os.stat() is actually looking at the wrong file.
When it doesn't exist, os.stat() returns a "no such file" error. Try
removing the string.lower() or moving the calls to string.lower() lower
in the code, after the call to os.path.samefile().
