Isn't making P2Pool big (let's say 50% of bitcoin total hash rate) a bad scenario? this will affect bigger variance(ofc not % one, you just get bigger timeframe in which that happens) and wait time for every miner, especially those small?
With 50% of total network speed and 10 000 miners (we have 10 000 ghashes/s so its even more than 20k GPUs mining) we will have 1 block every 20 minutes - so every 120 p2pool shares if i get them right. That will give miner a chance (assuming every miner is at same speed) of finding block equal to (20mins/10sec)/10 000 = 1.2% every 2 mined blocks in network.. to hit any block he will need to wait 166.66 blocks which is more than one day (1day = 144 blocks) for average chance of payout equal to his work.

P2P just lowers variance for everyone and speeds up everything by 60 times (1 share = 10s) comparing to normal bitcoin mining, but lets say we have 100k miners, what's then? Pooled mining will come back? Now think about those with Nvidia cards mining lets say 50mhash/s? Why they should join for 1 payout every week if they can get proportional payout every 30-120 minutes on big pools.
I know current pooled mining is dangerous and DoS capable, but isn't this idea going back to stone age?

Maybe i don't get idea properly. I just wanted to move here with my miners to support this project, but i see disadvantages in not so far future.

Please say i am wrong in these assumptions and calculations (i hope i am)! ! !



Sorry for my english, i hope you guys get whats the point
