If we want p2pool to grow, we gotta make firmware for the S7, which is basically all the new hardware being sold these days, especially to individuals.
I am using the S7 and haven't had many issue with running it on p2pool. All that was needed was to adjust the queue size.
If you want to hang around IRC there are a few of us there usually, we can work on fixing up some of the documentation around if possible.
