WinQ, a European WISP, has been working on a city-wide Wi-Fi zone in Kenniswijk Eindhoven in the Netherlands since July. The network uses Proxim APs and the Nomadix Universal Subscriber Gateway which enables customer acquisition and service provisioning.
The city center, cafes, hotels and the railway station are already connected. The city council uses the network to broadcast live city council meetings over the Web. The city and WinQ are looking at the project as an experiment to see how people will use the network.
It's a great idea to use a wireless network to allow people to be more involved in city government. These large Wi-Fi networks will be used more with useful applications like the city council broadcasts.
The announcement isn't online yet but should be up here eventually.
