Eli Noam's updated spectrum proposal

Eli Noam proposes what he calls a third way for spectrum — dynamic user fees managed through software-defined radios. Unfortunately, though devices capable of implementing this plan will someday exist, though don’t yet. It’s not clear when they will, or, more importantly, whether the overhead in complexity such a system requires will be worth it. Still, Eli deserves great credit for articulating some of the basic ideas of open spectrum some ten years ago, before most of us were thinking about the issue.
