I've had even more fun doing things with mesh networking (OLSR) as infrastructure for my embedded systems work. That is something we should be cultivating as a means of providing data connectivity between the average folks should the government attempt to seize control. Think of it in terms of an emergency 146.52 simplex network, but tilted to keep the computer users inside a community connected in spite of loss of connection to higher tier internet backbones. Even resurrection of the old NETROM stuff would be valuable inside a community in an emergency services context.
