I would grab "FilterProxy" from:
http://draal.physics.wisc.edu/FilterProxy/
I don't know too much about this program, other than it sounds perfect for
what you want to do.
It comes with a bunch of modules that probably won' tinterest you too much,
but it does come with a skeleton module, that you could most likely drop
your filtering code that you have been playing with, directly into it, and
immediatly have your filter.
