Anonymous P2P in a wireless mesh network
It is possible to implement anonymous P2P used on a wireless mesh network: unlike fixed internet connections, users don't need to sign up with an ISP to participate in such a network, and are only identifiable through their hardware. Even if a government were to outlaw the use of wireless P2P software, it would be difficult to enforce such a ban without a considerable infringement of personal freedoms. Alternatively, the government could outlaw the purchase of the wireless hardware itself, or require every wireless device to be registered under the owner's name. Protocols for wireless mesh networks are OLSR and the follow-up protocol B.A.T.M.A.N., which is designed for decentralized auto-IP assignment.
