If you are not concerned with keeping it CPU-only, then why call it "CPU only"? There are so many altcoins which have deceived on this point.
I can agree with the spirit of this, but from common usage on this forum "CPU only" just means currently a GPU miner isn't available. Usually someone comes along and develops one, often demanding payment to open source it. ASICs follow if/when economic feasibility allows. So it seems valid at least as far as the thread title goes. The CryptoNote developers' description of their PoW as "egalitarian" (implying true CPU only) is a different issue.
In any case, I changed it to say "CPU only currently".
