I've been thinking on howtoo solve the dust limit problem @OCEAN is facing. The simplest and most practical approach would be to follow the coinjoin model of having multiple pools for different size miners. Based simply on the hash rate the miner is bringing to the table, they would be placed in a pool that ensures their rewards are above the dust limit based on pools hash rate limit. 

Ex. You run 3 pools, A, B, C, with 100, 10, 1EH limits respectively. Then you can filter an individual miner to the pool where their hash rate falls between 0.1% to 5% of the pools hash rate limit. Or something along those lines. 

No accounts, no KYC. Just filtering based on hash rate only.
