Still a vast majority mining on one pool. If the developer is launching another coin in the coming months they need to find a way to manually or automatically limit what any one given pool or node can process at any time to less than 48% of all hashing power. There should be some way for the network to penalize them with a much higher difficulty than normal, this would either force the people to spread the hash or accept a reduced rate of finding for that node which would in turn encourage them to spread the hash rate and stabilize the coin base.
A miner with a high hashrate would be able to just spread out the mining onto multiple addresses.
But that would still help to prevent one pool from having a majority, a pool works under one address pooling their resources together and payment is made out later on. A single person would need to have multiple wallets if they were self mining which would make it more difficult to exploit the coin. The system would balance out as no one person would want to have a majority of hashing power, pool operators would try and self limit and single miners would not want to be over a majority as they would incur something that would prevent them from exploiting the system which would be much harder to do with multiple addresses.
I'm not proposing a reduction in hashing power just a way to help insure that it is spread between more than one pool or person. IMHO the more hashing power the better especially later on as it will only increase the value but having it all at one place only hurts.
