The bitcoin developers are effectively against p2pool since they are against micropayments.
Yes, I'm cherry picking the quote to respond to, and the rest I will get back with you on later, but this statement simply is not fair or true.
The lowest payment on the last block was 0.00168945 BTC
i.e. 0.68% of the pool.
If the pool was 1.5PHs that's 10.2THs
Thus 1THs would be ~0.00017 BTC
As difficulty goes up, 1THs payout goes down ...
I take it you think that 1THs is too small to mine on p2pool?
That's not entirely accurate... p2pool calculates share value based upon the weight of the share, which is directly affected by the share difficulty compared to the network minimum difficulty when the share was found. You are paid for however many weighted shares you have on the payout list when the block is found. There are far more miners on p2pool with less than 10TH/s than there are with more than that hash rate. For example, I've got a single S3 that mines on p2pool at 440GH/s. You can see my payouts over time for that rig. As an example, the last block, that rig made 0.00996171
