p2pool does not support random block rewards, as such running one will pollute the blockchain with undervalued coins. I chose not to go in this direction after adapting p2pool for PND some days ago, through reading multiple posts on getting the correct settings. I felt that as a miner I'd rather be paid correctly for a block found than be 'short changed' and as a pool operator, didn't like the idea of ripping miners off unintentionally due to to this limitation in p2pool. The maintainer of p2pool seems reluctant to code in support for random block rewards deeming it 'hard'.
Please don't pollute the chain with undervalued coins

Fair point but there seemed to be some demand for it in several posts. I think simply having the option is a good idea. We don't need to actively advertise it.
I also can't stop them from making their own config either.
