House to house mesh wifi network as emergency internet

Would it be possible to have a house-to-house mesh wifi network as an emergency internet?

Each house's wifi currently has sufficient range to reach the next house in urban areas, and with wimax technology, a house-to-house mesh network could be possible in rural areas. Combine this with home power generation (wind turbines, solar panels, etc), and there is a communications network that is resilient to disaster or attack.

Such a network could not easily be taken down by government to stop the populace communicating during times of government repression.

Such a network could also present problems for policing file sharing, as it would be outside the control of centralised telecommunications companies.
