Wireless Beach Access has already accomplished what Time Warner did for a faction of the cost. WBA is a small CLEC located in Delaware that has already WI-FIed Rehoboth Beach. They use DSL connections for backhaul for each of their hotspots creating a Metro Zone hotspot. You can use your WI-FI enabled device almost anywhere in the town, boardwalk or beach. Their yearly cost is 149.00 a year, if you rent your home renters are given separate usernames to access the network during their stay . The network allows two devices to connect simultaneously. One username allows for you to roam throughout the network. It is a Great deal for a Great price!
However, I agree it is only a matter of time before wireless Internet replaces all data connections including FTTH.
