This relates closely to the [Darpa Spectrum Challenge](http://archive.darpa.mil/spectrumchallenge/) that I participated in a couple years ago. The goal was to transmit information in a congested and contested RF environment. I think that they wanted to develop rapid spectrum-aware sensing as well as hard-to-jam signals.

I was literally talking about this yesterday with a friend in the context of military robotics and their control systems. He said those C&C systems would be a huge IW/EW target and my counter was that DARPA was already addressing that through things like the Spectrum Challenge.
