I had forgotten that NT supports forward slashes.
My only concern is that some of the config file values are
set programatically and I use os.path.join everywhere, so if the
config file is modified when running under Windows then the paths
will get \ separators and that will confuse the UNIX side.
I think I will still need something to ensure that the paths
are consistent... Hmmm... I wonder how evil it would be to simply set
os.sep = '/' when I initialize my application. I wonder if I will be
angering the dark lords of Microsoft by doing this.

I was going to simply remove the drive letter, so, yes, that would
disallow paths other than the curent drive. I might also map the drive
letters to a point on the POSIX path or I might do it Cygwin style
where C: becomes /cygdrive/c/.
