Actually this ZEC miner is a version of a dual miner I was working on. If you have the ETH kernel (which isn’t part of this release) you could dual mine with -k zec eth. The ETH part isn’t fully finished yet, but I could check performance for you. If it is good, I might release it. But I don’t think so, as both are memory hard. ZEC + SIA maybe an option, that’s on there partially as well.
