I would assume your are not talking about redundancy. You want to mine all pools concurrently?
yeah split hashing power
Well this is quite possible, but from the miners perspective very awkward, I guess is the way to put it. You can balance hash on miners across pools, but with beta rigs (or others) when it comes to offering hash, a miner will point toward a stratum that beta rigs gives out. Now considering beta allows this a miner to connect a balance load to two or more stratums then this would initially allow a renter to split hash.
