Using scrypt(N, 1, 1) means that only solo cpu mining will work until someone will fork mining pool software or implement GPU miner. All existing miners aren't compatible.
Interesting, definitely good to make CPU mining relevant again now that GPUs and ASICs have taken over all the other coins.
Will you post pre-release source in advance for verification? I think this makes it more trustworthy so that miners can review the code and only diff when the final code ships.
