What about failover support? Would really like to be able to lease rigs.

Failover in ccminer would be my preference to see as well so my cards don't go idle mining against NiceHash. If X13 makes it into the miner at some point, then multi-algo failover would be even better to have. In the meantime, I'm seriously thinking of building a C# app that can monitor NiceHash and then start or kill miner processes based on which one is best to mine at the time.
