Not sure I understand the utility of encrypting the miner/client, but that overall plan sounds great. Very fair release. I can assume Windows users will be included; someone else was asking about this, so I just wanted to clarify.
So the software can have a wide release without the first-10-people-to-download-profit-handsomely drama. If the code was available in advance, people would start mining right away. Although this raises the potential threat level that tacotime is fooling everyone and putting in a wallet stealer for every *coin out there for everyone greedy enough to just run the binaries at launch. I'd say that probability is pretty low, but it would be hilarious.
