This bounty will be paid once a working mining pool is deployed to a server provided by Invictus Innovations.
ProtoShares supports the GetWork protocol which should scale better given the harder hashing algorithm that limits the hash rate to about 1hz per computer. Because of the different nature of this proof of work you should not run out of nonce search space.
The bounty will be paid in BTC at the BitStamp price at the time of payment.
EDIT: I am canceling this bounty now that it is obviously more profitable to run your own pool than to be paid by me
