CryptoNight is not CPU only. See http://cryptomining-blog.com/2894-claymore-xmrqcnfcnbcn-gpu-miner-for-cryptonight-coins/ There is a proprietary miner and the dev gets 5% rewards from all miners.

Almost all CPU coins may be mined on GPU, it's just a matter of time.

I have a cool idea for algorithm. I will PM you...
