I just came upon this site savemuniwireless.org that focuses on furthering municipal wireless networks. There are lots of entries and analysis. The point of the site is to allow states/cities/municipalities to have their own wireless networks. As you may know LECs are fighting this trend as they consider states offering WiFi service — often for free, as a competitive threat. Currently the debate is centered on Texas.
A month or so ago it was centered around Philadelphia and TMCnet’s Bob Liu has an in-depth story on the happenings in the home of "cheese steak" and the "liberty bell" titled Philadelphia Unveils Citywide Wireless Business Plan and Intense Planning, Indoor CPEs Required of Wireless Philadelphia Bidders. (The author acknowledges that most people would probably list "liberty bell" first).
