[RC5] grid cloud computing

Following the general goals of idle computing, you would probably not want to dedicate EC2 instances specifically to running dnetc only. 

However, if you're already running Amazon EC2 instances for another reason it seems perfectly reasonable to try loading dnetc inside of them.  Amazon does not charge differently based on the percent CPU utilization of the instance (only by the hardware size that you select).  There will be a slight amount of external network traffic to the distributed.net keyservers, which Amazon does incrementally charge for.

Amazon EC2 does offer several different hardware sizes (the highest being an 8-core CPU at 80 cents per hour), but I haven't yet attempted to figure out which of their machines is the best in terms of maximizing your keyrate per dollar.

($0.20 x 24 hours = $4.80, so I don't know how you computed $12)
