Indeed.  Actually, I'd say that archives are more like *entire
filesystems* than either files or directories.

We have a pretty nice ZipFS implementation as part of the PyFilesystem
project:

  http://packages.python.org/fs/


If anyone cares enough to whip up a TarFS implementation it would be
gratefully merged into trunk.  (There may even be the start of one in
the bugtracker somewhere, I don't recall...)
