I like what I'm reading so far, this might be an excellent protocol to examine.

He has been trying to make it extremely secure and anonymous, and all communications are end-to-end encrypted. To me it sounds like the ideal protocol for protection against censorship and spying on the users.

However, I don't know how well it can be combined with a mesh network, especially one that wants to piggy back on the normal Internet, since this protocol is meant for a stand alone network. But perhaps it can be modified for that. It would probably be best to talk to the creator of the protocol about it directly and ask for his help.
