Bunch of open P2pool nodes on standard port:
111.69.243.158:9555
37.187.90.15:9555
95.85.19.109:9555
162.243.109.168:9555
188.165.19.28:9555
91.237.77.7:9555
37.187.25.91:9555
137.135.40.81:9555
85.214.22.17:9555
23.253.68.132:9555
Just check which one is fastest for you (low ping), check on page %local doa and %effie. If %effie is ~100% and %local doa <10% then node is not overloaded and can be used.
Check node fee under /fee most is 0%-1%
Remember to use -Q 0 on cgminer
Add few nodes as backup
-o ip:port -u D00ge -p wow -o ip2:port2 -u D00ge -p wow -o ip3:port3 -u D00ge -p wow
This way if node fails you will still mine on another one - payut will sum.
P2pool is ~200MH/s and block is every ~1.5h. For now
