Something else I've noticed.

I've seen a couple of "big" rig owners do a write up on the shiny new multi GH/s machine they just got. Both of them seem to just point it at p2pool for a few hours expecting the same steady rate of return you get from a traditional pool. When they don't see it within a few hours and they don't understand the numbers they see, they seem to wander off to the standard server pools constant trickle rate because it's easier to quantify.

Heigh ho. Maybe p2pool works better with and for lots of smaller miners who appreciate the returns more anyway. It seems a bit odd though when most miners claim to understand bitcoin technically that they can't get their head around a distributed mining pool model. Yes p2pool is another layer of "huh?", it is different, but that doesn't seem to stop it working for a lot of people.
