how can computer programers fix a political problem?
By making an underground network. Ad hoc, mesh networks....
grarpamp also mentioned mesh networks. I like how they encourage learning around radio signals.
Small watt transmitters can help stay under the radar of the FCC. I've worked out -- in a crude form -- some of the math for sizing transmitter power that the FCC won't complain about. Two key concepts are "heat" -- overall radio power (100 units of 5W transmitters is still 500W of transmitter power) and basic transmitter output which can be controlled downward until untunable at some fixed distance (like 1mile) so that no one can tell you're doing anything.

if you wanted to get really sneaky, i suppose you could record emissions from some other device, play them back at a high sample rate, and encode your information in 'normal' variations in their behavior. you could probably combine multiple devices to up your ability to mimic them with some wizardry.
