Where is WiFi Going?

Just a year ago I was expecting free ubiquitous WiFi to be available for all my travels. Now I am not so sure. It's long range cousin, WiMax, has also seen some setbacks. My IPhone is always on the lookout for wireless connections, and since many advanced phones have wifi, the demand is growing. Will it be government provided or entrepreneurial or poached from hotspots? Update: And wireless has more security vulnerabilities.
