Where is the miner protection program?
Only there is one significant issue with your miner protection / compensation program you seem to overlook.
If Hashfast could produce the product and ship as suggested in the example on their page by the 23rd October 2013, they would know for sure by now, baring complications once chips are in hand, whether they could be made.
With respect to the fab (TSMC), they would know now when they were likely to be squeezed in, as they have to run a hot lot to be in with a chance for that date, and they've only just raised funds to pay.
It's very unlikely that October 20-30th is achievable, and Hashfast would already know now for sure if it is, otherwise using an 'anticipated delivery of 20th-30th October', knowing full well you can't deliver by then, would be incredibly deceitful, especially if one raises funds under the guise it's almost certainly achievable.
So deceitful you may not want to be held accountable by a third party secured payment provider like Paypal, or a plethora of card issuing banks, or offer refunds until 3 months later, perhaps limiting refunds to a two week window, sharing what little amounts would be left after expenses. Not that I believe they are likely to fail, they've taken the money from people who now can't get it back, I believe they know they will be late, or they could tell their customers for sure now when the fab has promised the chips by. After all their customers are already under NDA and deserve a right to know, if such information is to hand, which it is, because the miner protection plan means nothing if you're left faffing around paying and waiting in line again for others to make a second machine with a raw chip, whilst Hashfast deal with the order of their backlog, and possible delays, and the real winners got a significant head start weeks earlier, if they get to receive their goods in time.
Miner Protection Plan seems like a marketing ploy to cover something they are concerned enough about, to withold access to third party consumer protection, and refunds from.
Also, what makes you think the KnC chips can't be clocked? KnC have only promised 400gh/s, with margins upon margins, upon margins. That sounds like potentially a lot of room to play...
