Developers of new alt-coins should also release the right p2pool config immediately when a coin is launched.
This should become a standard practice, so that every p2pool node uses the exact same configuration creating one homogeneous mega pool. I've seen multiple p2pools for the same coin because multiple persons create different configurations. P2pool is pretty useless if the nodes for the same coin do not all act as one.

I like p2pool a lot but I still fail to find correct configurations for new alt-coins.
