http://gulden.p2p.0x0a.nl:27100 is accepting shares and running on the latest wallet (v1.1.7.0). It's been about three weeks though since anyone came along to mine  By the way, I'm using Spekske's p2pool source from https://github.com/Spekske/p2pool-rav except with BOOTSTRAP_ADDRS set to gulden.p2p.0x0a.nl since Spekse's p2pool server is no longer running. I hope to put it up on my github later this week so that it's easier for others to set up p2pool nodes - p2pool can use a little push
