Julian Priest made an *impressive* study (http://informal.org.uk/people/julian/publications/the_state_of_wireless_london/) of how wireless networking in London has developed over the last three years from hacktivist pastime to mainstream pursuit. He compares networks built by freenetwork groups, commercial hotspot providers, and public sector initiatives; he examines the sales and uptake of WLAN equipment; and he makes some direct measurements of wireless activity in the Greater London area.

Overall it is a must-read for everyone who is interested in the definite uptake development of WLAN technology.
