This seems to be overlapping quite a lot with the recent discussion on
object-oriented paths (
http://mail.python.org/pipermail/python-ideas/2012-October/016338.html) and
this question of how paths are represented on different systems was
discussed quite extensively.  I'm not sure where the thread left off, but
if PEP 428 is still going ahead then maybe this is something that should be
brought into it.
