Ugh. There would have to be a lot of intelligence built in, or the things would go into a state where one change would trigger a ripple effect where channels were constantly changing.

Protecting a licensed band for some industries (e.g. healthcare, or SCADA controls) might be a good thing.

There seems to be a gap between what people think is there and what you get when you try measuring it.

Again, it depends where you are, and what you are looking at. Sure, in some areas, you may have 25 people in one build using ch. 6 and no one is really moving a lot of traffic, so that it isn't congested based on the time bursts. However, add a couple of people downloading ISOs or <gag> using a P2P file sharing (mal)ware, and you can have a real mess.
