Is the new idea like the smart contract?
BTW, I just checked the pool leaderboard. It looks like the pool can use one workerid for multiple miners now:
inblue blu-a11 5818.9(HPS) 721669.92(HPS2) 1334(shares)
Some changes on the pool code?
You've pretty much been able to use a single workerid for multiple miners for a while, it just shows the HPS of one miner and the HPS2 is the aggregate of all miners using that ID. No real advantage or disadvantage to doing it.
