Free Municipal Wi-Fi

I was fascinated by Wired Magazine's map of Free Municipal Wi-Fi across the United States. I knew about some of the bigger initiatives (San Fransisco, Chicago, etc.) but I had no idea how many other towns and cities are working on providing free, government-sponsored wireless access. I guess in some ways it makes sense, since free municipal Wi-Fi seems like it would be much easier to implement on a small scale. I'd love to see some global information about cities going Wi-Fi.
