I just hope the gpu miner will be made public opensource, otherwise there will be a massive pre-mine that could last for weeks. 20% over 4 years will be in the original investors hand already, centralizing it even more will destroy the reputation of the coin.
I can think of a few coins destroyed by a closed source gpu miner used at launch. Only one person with the gpu miner could mine the coin, and although each dev denied it was him nobody believed it. Who else could get the gpu miner coded instantly after the first block?
