Almighty Lightweight Fact Remote Exchange Daemon

A.L.F.R.E.D. gathers status information in networks with dynamically chaing topologies, e.g. a Wifi mesh with mobile clients. It is a user space daemon for distributing arbitrary local information over the same mesh/network in a decentralized fashion. This data can be anything which appears to be useful - originally designed to replace the batman-adv visualization (vis), you may distribute hostnames, phone books, administration information, DNS information, the local weather forecast ... Users may insert information by using the alfred binary on the command line, or use custom written programs to communicate with alfred directly through unix sockets. Once the local data is received, the alfred daemon takes care of distributing this information to other alfred servers on other nodes somewhere in the network. As addressing scheme IPv6 link-local multicast addresses are used which do not require any manual configuration. A user can request data from alfred, and will receive the information available from all alfred servers in the network.
