very true but p2pool has other issues that cost miners revenues (I mean beside the work running the pool themself and keeping it up to date / state of the art..) e.g. with increased stealth rate .. or is that solved already?
It's been performing equivalently or better than any "standard" pool for months now. The recent upgrade to v9 has increased the stale rate, but that doesn't seem to have decreased the number of blocks it finds.
