Each python M.N.X has its own byte code for distinct values of M and/or N.
So, if you had a shared directory, not only would your users have to
be able to write to the shared directory (when they import mumble, and
mumble.pyc or mumble.pyo has been generated by a different version of
Python, they will recompile mumble.py and rewrite mumble.pyc (or .pyo).
