"Clever," and "stupid" are value judgements, and therefore aren't
really applicable here. In my limited experience I would say that you are
on the right track, what exact kind of feedback are you looking for? I
really doubt that you'll get any responses that would include code, so I
suggest that you get to work and let us know how it goes. :)
Good luck,
Doug
