I had a vague idea about setting up some Amazon EC2 high perf servers with GPU processors as bitcoin miners - I did a little research and it is possible but it seems the Amazon ones are pretty crap - Even with the GPUs.
There are other cloud servers available with GPU procs and people looked into it a year or so ago - They did the calculations and it would not have been feasible - You would not have broken even.
However, it was not that far out - Just a few percent.
With the massive jump in value of BCNs it should be pretty profitable by now.
Its to technical and to expensive for me to take the idea any further but could be worth some more research for someone with the resources....
Just remember me if you do become rich
