For DOGE have you thought at all about running the cows through another larger pool? We would lose 1% or so from those pools fees but it would give very steady returns in theory... Could easily be calculated into the profitability. I don't know how hard this would be to implement, but on another coin switching pool i use, when we are mining DOGE usually the user with the top hash rate is "wmpool" and has about 150mh/s I was assuming this was another pool using the larger pool to stabilize returns on larger network coins.
