I think that's a great idea about a community piggy bank. We did try to get a maemo.org paypal address set up for the first competition but it never went anywhere, thankfully zehjotkah stepped in as treasurer. It seems with the new Hildon Foundation/community/whatever we turn into there will be a board that has the ability to raise and hold finances so it should be doable then.. I guess? It's up to whoever ends up on the board I guess.
