The problem is even high end ATI GPUs will only generate $.50 a day and that will only get lower as the network becomes after. Anything else generates less than $.05 a day which isn't worth it at all. A network specifically for this could never be set up either as there is no incentive to pay for the GPU time except when it's directly performing something useful i.e. bitcoin mining.
