One of the interesting themes developing in the "community bandwidth" world, from Champaign-Urbana to Reykjavik, is the idea of the community network as a local common carrier rather than an ISP. From Steve's notes on a site visit to Champaign-Urbana Wireless:
They are setting up node antenna kits around Urbana with 802.11a backhaul and 802.11b access point in a mesh network configuration. They are NOT setting up access to the internet, they are creating a network. If the "owner" of the node wishes to share his broadband access, then there is mesh connectivity to the internet...
"We look at a community network, not as getting internet to the masses, but as making the community its own internet." --Zach Miller, SW egr CUWiN
