I finally got p2pool working again! MrData helped me tremendously on IRC by figuring out what was going wrong protocol-wise, but there was still a little issue with hash target sizes which seems to be present in p2pool-rav itself for scrypt coins.. There are just a couple different files with a handful of differing lines, but it's enough to cause some trouble. Since it's working now I'll try to figure out what the important part is so I can commit it to https://github.com/CryptographicAnomaly/p2pool-rav, but it won't be before tomorrow. In the meantime, you're welcome at http://cga.p2p.0x0a.nl:6966/ (I've lowered the fee to 0.5%)!
