FON - Network of Wi-Fi Hotspots

This idea makes a lot of sense.

From CNN.com:

Aiming to increase access to the Internet, particularly for people away from home, Google, Skype and other leading Internet investors Sunday announced a $21.5 million investment in an innovative new Internet access network called Fon.

The company, founded by Spanish entrepreneur Martin Varsavsky, aims to build a network of WiFi hotspots far larger than those from companies like T-Mobile and Swisscom, none of which have more than 30,000 hotspots worldwide.

In comparison, Fon seeks to grow to one million hotspots in four years. First, Fon needs to overcome the hurdle of existing service agreements users have with their ISPs. Negotiated shared revenue should encourage participation.

Fon will seek to make its money by charging non-members for use of the network. Even so, it's expected to be cheaper than what existing wireless ISPs charge.
