The Federal Communications Commission (FCC) has granted Google the application to use the whitespace spectrum ( along with several other companies).
White space spectrum, or super wifi, or even wifi on steroids as it is sometimes called, has a much longer wavelength than traditional wifi, furthering it’s reach with much better penetration, some initial research showing at can reach over 50 miles.
Here is a video of one of Google founders, Larry Page, speaking about super wifi , http://googlepublicpolicy.blogspot.com/2008/05/larry-page-talks-about-googles-vision.html

Combined with mesh networks this would be a game changer, of course the tech would most likely still be currently run by the telco’s and Google, but I am positive some open source ad hoc solutions come out of this new field.
Providing local information during an “internet kill switch”.
Due to recent events in Egypt and the speed of the shutdown.
Most of these projects are open to contribution and further development.
