Second question. Someone in this thread disassembled the KNC firmware (can't find the quote) and found a 6 module option. Is this form factor in construction at the factory?
Well considering there are 6 controller ports to plug into I would say yes that is in the future.
I wish I could find the quote. The firmware option had Mercury, Saturn and Jupiter as the 1,2 and 4 options respectively. The 6 option had the word "hosting" in its title, suggesting that there might be an undisclosed configuration, perhaps only available to large hosting customers, such as Cloudhashing. It's probably just conjecture, but would be nice to have official confirmation, although Bitcoinorama stated that no such units are currently being built.
