The prize is $10000 for each miner and it has to be open source. Good luck getting Claymore involved... 
Yep, but I have no problem with a dev fee. Didn't bother me with ETH, won't bother me with Zcash!
eh you can't have both, if it is open source, a fee will be useless
Don't know if I am explaining this well enough - of course Claymore would be closed source with a dev fee like his other miners. He wouldn't qualify for the "Open Source miner contest" if he used his to-date business model.
yes but what would be the point in using it? if it is no faster than his own fee, or it's not adding dual mining...
