Great idea. Thing is, it is one thing to give instructions on how to do it and another to actualy hand a file or disk that includes the required data. There are a lot of copy right issues involved, are you paying for it, who gets the money, me or uncle Gates, what about the license? can I give it to you for free? no, I can't even if I payed for it, it is like downloading mp3 and sharing and, and, and... you get the point.
Wish it was that easy.
