I'm getting annoyed by these guys charging a ridiculous 2% of all our profits. I coded an rpc proxy for equihash which i'm using in our farm. I will add functionality to report hashrate for each client connected to the proxy and will then open source it. The proxy impersonates a single miner and hides the actual miners from the pool. It relays the job sent by the pool to all proxy clients. At least you can be sure they all mine the same share, start at the same time for each share and have the count done locally. Sadly, because these guys closed sourced their miners, you can't control the seed they start with for each share, so luck will STILL be different between dstm and bminer ... i.e. you will still need to wait a long time for reliable results, but at least I can compute total average hashrates, rather than only 12h or 24h.
If bminer is cheating, I want to expose it. Will look into this next week when hopefully I'll have more time. I stopped using bminer after doing my dstm vs bminer test.
