Hashing demonstrations could be faked since all you really had to do was get hold of a few Avalons and hide them somewhere ;P
Id happily preorder if I could come pay for it in person on pickup (hey it's like 2h by train :p) or pay for it at delivery, if you expect deposits for preorders then you will have to provide some impressive proof that your product is real.
I'm hoping you are real, even wishing it! Can't say I'm looking forward paying import tax for my BFL/Avalon orders and having an ASIC company so close to home would be awesome.
