It surprises me how naive some people are in relation to these issues...
Nlsupernova - In regards to KnC go and have a look at this video:

There is no hiding, and the cat is already out of the bag... It is completely open to everyone what is happening.
There is also no hiding on the network, these companies are the elephant in the room!
It is the perfect business. You mine with the new miners while they are still the most profitable and when it starts to become more marginal you ship them to your customers. You then develop the next generation miners and the process repeats itself...
So I suppose everyone will stop buying ASIC miners from KnC now that I have "let the cat out of the bag"!? why shouldn`t they be allowed to build their own center to use their equipment long term? if they build that just to mine for a few weeks with customers equipment and then shut it down again when units are sold i still doubt if there is a decent margin.
things arent always what they seem to be. just because you can cheat your customers, doesn`t mean that you will.
but having the faccility in place allready for long term mining does make it easier and cheaper to scale if they wanted to do it.
