I'm concerned that the company has all this hashing power in their data center to give out.  They just promised to offer hashing power of their 28nm equipment to all preorder customers.  Call it 3600 units at 3th/s each, or 10,800 th/s or mining power.

Originally, KnC's company mission was to only mine with 5% of what they produced for their customers.  That would mean that the company, after selling about 7,000th/s of mining power in 28nm chips, should have only about 5% or 350th/s on site in their data center....

Even if you assume the company delivered the entire network in hashing power, 18,000 th/s at 5% is only 900th/s on site at their data center.  How does a company that promised to only have 5% of their customer's orders hashing for themselves, have the equivalent of 10,800th/s mining in their data center to give out to customers....
