What is ASICMiner's bus factor?
This is an excellent question, a pity it was ignored.
Or, it was ignored because maybe nobody knows the official answer (since the inner workings of ASICMINER aren't exactly clear), or because it is known that the bus factor is 1.
Just guessing.
(disclaimer: mind, I love ASICMINER, only sometimes things like this one worry me)
