No need to modify site.py.  Either create a sitecustomize.py in your
site-packages.  Here are some references:

http://docs.python.org/library/site.html
http://www.python.org/dev/peps/pep-0370

Nothing new is needed.

As to metapath hooks, one alternative is to make a helper function
that puts the hooks in place (or otherwise manages your hooks).  Then
you can call that API in each script that needs those hooks.
