CommunityBroadbandNetwork

A Community Broadband Network is a network that connects members of a community together at high speed.

You can do lots of things with such a network -- high-speed file transfer, shared internet access, video streaming, voice over IP, backup. Some suggestions are at NetworkServices.

These guys http://nocat.net/ are doing a similar thing so might have info that would come in handy (DaveRobinson 2005-12-24)
