I think you should not overrate this 51% attack: http://www.youtube.com/watch?v=Lx9zgZCMqXE . As I understand it, when one node gets close to the 50% you can start scamming, but this does not mean, that someone is able to create coins, you just can change the addressee off a made transaction.  And: feelleeps pool itself is a powerful node, and now the second powerful one is surfer: so if you want to get rid of this 51% attack problem, we need more pools or single nodes with a lot of hashpower.
