If you could get a zoning waiver or tower space you could run a 20mbit ds3 and serve wireless to your neighborhood. Would need about 20 subscribers - at $100 a pop, a couple U's in a rack somewhere for RADIUS/DNS/DHCP/Authorization processing running under a hypervisor. After all - how fast is the fastest cable in the hood? You can promise 10mbit and deliver 20. So long as your vigilant and run accounting to find your troublemakers you could make this into a serious moneymaker.
