Since algo is scrypt, what about merged mining? You don't use any more that what is already being used for scrypt. doge is doing this with litecoin... there's no problem with hashing power there.

dev has this put energy into these rasp pi miners, so using low cpu method to mine is important. merged mining wouldn't help with that, but PoS could work. Again, that means only former kittehcoin owners benefit. Even if low reward stake, no one has any quantity other than previous MEOW coin owners. Or buy on exchange...
