content: That's a good point, and I agree with you overall.  I would like to point out that ISPs are an entrenched industry, and there's also the desire to not change the status quo or upgrade networks beyond what is absolutely necessary.  They've maintained power by keeping new players out of the market, and that might be harder to do with wireless long-range systems.  I'm cautiously optimistic, but I do understand there's a good chance this will turn into nothing.
