Wireless mesh networking is the key ingredient in making the dream of municipal WiFi a reality. That dream is a little closer with the adoption of 802.11s. Until recently there was no standard available for early adopters to use so they were risking alot if things changed from the method they were using. The lack of any in-fighting or competing proposed standards in 802.11s seems to be a rare event. This means that it should pass through quickly and we should see mesh networking gear on the market about a year from now.
