good answer ...

basically it would benefit the pool as a whole if we had that much hashing power in the pool as we would find block more frequently and would be rewarded based on the percentage of work done. A large miner would be facing a higher difficulty than a small miner so the small miner would have a greater chance of getting shares. Frequency of payouts would be greater and is where the greatest benefit would be even if the pay outs are smaller. In the end it would even out or be greater than what the pool is able to get right now with the hash rate being so low.
