I have been following this thread with great interest. This last point highlights a concern I'd have .....while I in no way whatsoever begrudge the creator charging a little or even a lot of beer money - its awesome what they've done, I wonder about sustainability. It's a lot of building to undergo and be dependent upon the goodwill or even availability of one person and their hobby.

What options would you have if he was off the air and you either fried your last chip or wanted to start a new build?
