+1 for this

uWSGI started with module-approach configuration only (as gunicorn) but 
i added support for wsgi-file as soon as i realized that file-based approach is a lot more useful/handy
(no need to make mess with the pythonpath or add __init__.py file all over the place as Graham said).

Pinax (as an example) has a deploy/pinax.wsgi file that you can use as an entry point for your app independently by your filesystem/pythonpath choices.
It worked (at least for my company where we host hundreds of WSGI apps) 100% of the time and without users pain. I cannot say the same for the module approach
(yes, a lot of users are not very confortable with PYTHONPATH/sys.path.... probably they should change work but why destroying their life when we have already a solution
working by years :P )
