Robert Cringely in his column on PBS describes how Canadian Andrew Greig put up an open WiFi accesspoint for his neighbours to share. But he takes it a step further. He also shares telephone services and TV-signals over his WiFi. In a sense he turned his WiFi into a telco backbone, which the neighbourhood uses much like a cooperative organisation. Interesting thought. I share a second accesspoint in my home, for passers by to use. How might one build on that….Andrew Greig opens up some interesting vistas.
