This free software project needs some love. It is the only one that with GNUnet is addressing the problem of Sibyl attacks on DHT (http://secushare.org/anonymity) and it is being built using gnunet + PSYC. I love the detailed documentation and the long-term thinking about how to build a truly good internet. (And it works over ad-hoc mesh networks!)
secushare.org It is also not profit-driven venture like MaidSafe seems to be (MaidSafe is a company), plus MaidSafe is using DHT routing like the other ones [https://github.com/maidsafe/routing]. Also MaidSafe calls itself "open source". Anyway, I was wondering why I don't hear more about this. Maybe nobody knew about it - I sure didn't... It wasn't listed on Prism-Break.org for some reason. Free the airwaves!
