Why, I bet that Xilinx will sell me FPGAs for free! That way if I want to buy ten times more, it won't cost me ten times as much! And I bet no one thought of that idea before -- why, I bet when people came up with estimates for the price of a piece of hardware to execute djb's algorithms they never thought of parallel processing at all.
