So I finally got p2pool up and running but I'm having trouble getting consistent hashrate...it was initially getting up to 2.9Thash for two units (about 1.45Thash each) so similar to Eligius but then it tanked to 2.3xThash for both and after a lot of messing around rebooting the units I managed to get it up to 2.6-2.7Thash for two units.  One unit is now doing 1.3Thash only apparently, grr.
