As I understand it what makes p2pool DOS resistant is the fact that there are many nodes running. To be effective a DOS attack would require most of the nodes to be overwhelmed simultaneously. An attacker would have to determine the most effective nodes to attack to disrupt the network. If the network is adaptive enough it will reach out to link with other nodes that are not under attack maintaining integrity of the network. A Centralized Pool which only has one or two access points would be easily over come in a DOS attack because the attack can be concentrated to limited access points. The more spread out things are harder it is to disrupt. so arguing that consolidation is the best option is an faulty tactic as demonstrated by the Japanese at Pearl Harbor. If you both want to consolidate under your banners your both wacked. The more nodes running the better.

I think you are mostly arguing semantics.

Wake up and smell the coffee. If people here wanted to be in a centralized pool they would already be in one.
