I agree with Atheist. If we were to cut it at block 133700 and make it pure POS after that. We could start a few pools which would mine other profitable coins and sell those coins for nyan.
That's a great idea, this way miners can still mine to get NYAN and at the same time, it would increase the value of the coin.
It is a similar model to that of blackcoin which mined everything inside the first few weeks. By having a "multipool" hash other profitable coins and take that btc to buy nyan it will both drive up the price of nyan as well as increase volume on exchanges.
