This may be true for you and your community, but where I live, where lots of people can't get stable modem connections, and can't connect faster than say 14.4K, there are people screaming for alternatives. We have lots of wireless "home" customers for lots and lots of different reasons, and most of them are not in the geek category. Our community is extremely low density population pockets, and delivering wireless over extremely diverse topography presents extreme challenges, and in many cases the up to $20K installation costs are offputting to the customer.

Problem: If you can't get better then 14.4k connections, how are you going to internet feed your wireless POP? Telecom does not install frame connections on poor copper due to QOS SLA's. That is where the 20k install cost comes from. (Which I guess you are well aware of). Though given all of the costs involved, do you actually make money supplying home users in low density population areas?
