Don't take this the wrong way, I do not think mining is going to die out as soon as some on these forums say. But I do like to think of what we will do with the hardware "after" bitcoin whenever that may be.
Basically I'm looking for any other opportunities to rent out processing power, are there any out there? And if not perhaps there is a market to set up a system for brokering the trade of processing power for companies that could use it?
