Thanks for your comments, and no offense taken. The reason we aren't going down alternative routes is that VC companies aren't too keen on financing asic mining project for the public to make money from them - they want to keep them in house to mine themselves, and that's not our ethos. The amount of money we need to even get to chip prototypes is simply way more than all our combined resources and then some, so this seems like a logic route.
We will never comment on how other companies conducted their business. None of us were BFL customers so have no knowledge of the quality of their service or products, but there is no argument that their products did (eventually) make a lot of people an awful lot of money. That's no excuse for poor service, but it is fact and we like dealing in facts.
I disagree with your opinion that a VAT number means nothing, but you're entitled to it like everyone else. How you enjoyed reading out pitch.
0.3W/GH at system level from a 40nm chip is indeed very nice. What is the power consumption at chip level?
It comes in at about 0.17-0.18 Joules/GH running at spec'd voltage of 0.85V. You can get it down lower, but the internal delays go way up and so the clock speed has to come down. It also gets more difficult to predict timing.
