And considering people are saying this coin is no longer currently profitable to mine with EC2 instances, and afterwards the hashrate triples or something to that effect this morning, I would have to conclude someone found a way to write up a GPU miner.
Look above, crypto_zoidberg showed there is overwhelming evidence it is ec2 (and someone said 60% of their peers were amazon). The sooner the public GPU miner, the better. That would make net hashrate much more stable, and if someone has a private GPU miner, level the playing field.
Wild keccak algo in the works?

looking into it.
