Calling the BATMAN: Free Networks on FreeBSD

BATMAN (Better Approach to Mobile Ad-hoc Networking), as developed and used by the Freifunk project, is a routing protocol for (primarily wireless) multi-hop ad-hoc networks. Freifunk is a German initiative to build an open Wi-Fi network at city-scale, based on the principles of net-neutrality. BATMAN's motive is to be a completely decentralized protocol; no one node in the network knows or has to care about the topology of the whole network. Support for this protocol is provided by the batman-adv kernel module on Linux, and, with this project, I'd like to bring that to FreeBSD. This will include the kernel module itself, but also userland networking libraries and tools necessary to create BATMAN networks.
