I will give 1000 tasty internet cookies to anyone who can find a short comic/pamphlet which explains how the spectrum is regulated and how it could be greatly improved. It was a great and simple explanation with pictures, but google fails me and I can't find it.
This is good but the one I'm looking for was more like comic. With examples of how say police monopolize the spectrum for emergencies now,and how they could still get priority in a more dynamic system.
I can tell you that the amateur radio 220MHz band was de-allocated and handed to UPS. I can suggest to you that that was true to a pattern - see Joseph Stiglitz: http://books.google.com/books?id=yxhV44nSN_4C&pg=PA110
