Or the router devices and/or portable devices could form meshes to get extended range and more of an internet/Internet. The simple case isn't hard. I've been thinking of doing the same thing for Burning Man: Resilient, mesh, usually disconnected, store and forward when disconnected, secure + public, fair, prioritized traffic, opportunistic but bulk Internet capable networking in harsh environments and random usage patterns. Add store and forward to an XMPP server, plus email, some file transfer and usenet like flood propagation (using bittorrent protocols/methods), and you'd have a nice independent communication network. Layer authentication / crypto, features, and applications as desired. Stephen References 1. http://news.cnet.com/8301-1009_3-57605233-83/john-mcafees-$100-d-central-aims-to-outsmart-the-nsa/
