i'm not sure about the specifics, but i applaud any attempt to return something to contributors. There are difficulties as always. The most important I think is that it might discourage free contributions if the core developers got paid and no one else did. Second most important is how to handle payments made to one project, when it uses similarly licensed software from another. If the purchaser had to pay double and the money were split we might have a new industry aggregating software. If those hurdles weren't fatal, I might consider a simplified pricing model: say $X for commercial use, free for other uses, coupled with a system for handling the payments. Otherwise the payment part might be onerous. I call my new license "Fee and Open" Source.
