we are still shopping around for a long term manufacturer of these asics
Not trying to throw the hate on or anything, but I do know quite a bit about ASIC manufacturing, and if you're still shopping around for a mass manufacturer, your delivery date is at least six months away. Are the first units in December doing to be wafer sharing runs? If so, how are you getting the density to do 27 GHash/s? Assuming 300 MHz transistor technology - which might be available through a wafer share - a 27 GHash/s unit would require something like 100 million transistors. That's not wafer sharing territory...
