I would like to suggest people to not add more hashing power to guldenpool, because it approaches the 50%. Criptoe is a nice alternative.
Second, I think someone needs to weed out the dead pools on the first page.
Indeed,
http://guldenpool.nl:27100 is pretty much maxed out at this point. As I told a certain friendly member of club1680, I do have another node setup at
http://node2.guldenpool.nl:27100, but AFAIK it would still be feasible to perform a >50% attack as long as I have control of both daemons. If anyone wants to set up another p2pool node, I'll gladly help out!
