> data caps (which make sense given the limited actual frequency bandwidth available for radio in free space) Time -- or better, demand-- based rates would make a lot more sense than caps for that purpose. If you note most cellular data caps ignore the providers own services or various partners (like youtube). I'm not saying that the cellular rate structure has nothing to do with the limitations of the last mile physical medium, but it would be an error to assume it has too much to do with it either.
