First of all, hello everyone, long time stalker but first post here
This Mystery miner - would Compute4Cash be a candidate for this? They pay for "WorkUnits", and do not explain what they are used for, the calculations are done with GPU's and they even have a list of WUs/hour for various cards which greatly reminds me of the wiki list for Bitcoin...
A brilliant idea from the owner idd if it is; pay people a fraction of what they could be earning with the actual pooled mining and rake in loads of profit for yourself ;p
