Île Sans Fil (Wireless Island) will disseminate audio and video through its community-based free Wi-Fi hotspots in Montréal: Using content cached on the local networks, visitors to any of the 11 initial hotspots equipped with HAL (Hub des Artistes Locaux or Local Artist's Hub) can use iTunes and other music players to listen to music or watch videos. The project is supported by local media and culture organizations, including CHOQ.fm and CUTV.
HAL isn't just a local project. Rather, it's the local outgrowth of the open-source, commodity-hardware-based modification of the Firefly Media Server coupled with network software to allow network advertising (in the technical sense), discovery (in both the technical and artistic sense), and sharing (in all senses).
I am not alone in noting that the power of a Wi-Fi network can be in the "local" part of the WLAN (wireless local area network). While city-wide Wi-Fi networks might guarantee 512 Kbps or 1 Mbps of access, a WLAN in a hotspot could deliver 20 to 30 Mbps of net throughput.
