If it's worth doing, then someone should do it commercially. Port it then sell the actual hardware with it already installed. The reason why Castle is successful is because they are a business... everything they do makes money. That's their incentive. A bounty, or donations scheme, is hardly incentive. Making profit is. SO I propose that if a programmer, or group of programmers would like to do this, they make a business plan and execute it and make some money. Making money attracts others and that benefits everyone and then you have a real marketplace.
