This is the whole problem with current pools, they should all be p2p! I have used other Max pools and don't get half the coins as on 1gh. As a single miner I can't change that. Question is why don't some of the big Hasher's change pools?
There is a maxcoin p2p-pool in the works. The situation is not ideal right now, but bitcoin had the same problems for a long time in it's early days.
As long as 1GH do not use their majority share of the network for nefarious purposes, it poses no threat to MaxCoin. And if they ever did, they would lose their profits from the 3% mining fee they are currently taking, as the hash power would abandon their forked chain in favour of the developers fork. In game theory speak, this is a stable nash equilibrium.
