No.

I've been wondering about this too.
How do you prevent rouges setting up hundreds of nodes that collect data about transactions, without a financial barrier to disrupt the network and create many men in the middle sniffing transactions as they pass around ?
Yea, that's why DRK's masternodes are not an ideal solution... because it is a centralized solution.
I don't think it is centralized at all. You mistake rhetoric for agreement to a view that is given without thought.
