Testing your pool - works fine on my laptop with cudaminer but when i try mining with an AMD graphics card with cgminer I just get hardware errors 'invalid nonce count - HW error' - any idea why??
If you get a chance, give that another try -- I followed a couple bug reports thru GIT and I got my CPUminer to act right - so that should solve the GPU miner from having hardware errors... (was getting same issues with CPUminer you were having with ATI/AMD (OpenCL) miner) - maybe this will work. Just set any XNC address for payout - it's running on my 8.7.1 xencoind - so it should payout - so long as it wins some blocks - or I'll have to sort something out for ya for your time - I don't have any big mining hardware and so I don't generate coins anymore --
If this fixes the issue with OpenCL miners, then I'll update the GIT with the p2pool code -- then some more p2pool nodes can go online. I won't be compiling a windows binary though - not anytime soon anyways...
