With Spondoolies selling 110TH/s machines that consume 0.15W per GH/s only to large players, I really do not see how small miners are going to survive at all.   We are now dividing up about a block a day amongst us all.   If a minimum order is 15-20 machines (like the rumors say), each person that buys into Spons will be adding 1.7-2.2 PH/s all by themselves.   At some point the amount you receive gets so insignificant that you do not care.   I find it all kind of depressing.
