I personally do not see why we cannot do an on demand availability to items which people need to complete a restoration (regardless of if they where in on a group buy or not) via either something similar to the ROM burning services or make items available online privately for the person via FTP/web. This would allow some element of control over the entire set not being used for profit making.
Just my two cents...
And a very valid and interesting two cents it is! I've no doubt that we can do that.
Lets get the purchase done and dusted before we start debating this though. Priority one, is get the files bought and paid for.
EDIT: UPDATE!However!! On another interesting note, there is a move afoot, to further reduce postage costs and distribution time to the guys buying into this in the USA.
To that end, the Hard drive containing the master files, will be making a little diversion via New York on the way to the UK. "Randy. T." of "Groovy Game Gear" fame, has offered to do the distribution on the US side of the pond. Personally I can't think of anyone that is more respected and trusted in this community, and whose record of prompt and efficient delivery is known to all here.

Thanks Randy!!
This will massively cut the postal costs and reduce the risk of drives being lost or damaged in the post, for the guys in the USA. It will also allow me to concentrate on the UK and European distribution and cut the workload.
