Also note that per the TV news today on Walmart Superstores, they are outlawed in Los Angeles and even the smaller Walmarts will have to undergo special restrictions and meet certain community regulations. This is because the Walmart Superstores have created large low income government subsidized families of workers because of their minimum wage employee policy. They have also decreased the taxable income for the cities they are currently in by lowering property values in the areas they are located in. There may not be many Walmarts or Super Targets to fund such speculative technologies. I'm on the side of putting together a buildout of WiMax for a publicly owned and operated system that is designed, managed and implemented by a consortium of technologists. Additionally Churches have nice Steeples. I was in one a week and a half ago. I could see Catalina from just East of Western on Santa Monica. Also Pacifica and other public radio stations seem willing to let us use their existing antenna locations or at least talk about it at this point. The other church I'll be going to sits atop of the Loyola Marymount University property. It can see to Downtown LA. Whith this kind of community support it will be very difficult for any private enterprise to compete.
