I've been thinking about that as well, it's a phenomenal opportunity. I live in a place without DSL or digi-cable and there are many like me. You could tie in home networking and offer a complete solution.

What you need to do is secure cheap space in relatively tall buildings to put up the transmitters. As of now there is little regulation of the broadcast end of things, so that won't impede the startup by adding administrative costs.

The main tactical problem is making sure everyone likely to be a customer has line-of-sight to one of your transmitters.

This is also a phenomenal growth opportunity for hooking up people in the hinterlands. In a way that would be an ideal business - travelling the vast expanses of the West, putting up networking.
