The ADF issue is a non issue. Obviously we would all be building these to play the highly acclaimed Cinemaware games that are being freely distributed by the legal copyright holders, and every one of us will be buying our kickstart roms legally from Clanto. This means that Amiga will actually get paid for the bulk of the MiniMigs sold.
In all reality, I expect that there would be very little piracy of Kickstarts, as I would guess that most of the people that would bother to buy an actually MiniMig would also be willing to buy Amiga Forever. Those that want an Amiga for free will just emulate on there PC.
