WiFi in as many places as is feasible.  That seems to be Boingo’s mission. For 22 bucks a month, you can get your laptop on Boingo’s network, which is arguably the largest WiFi access network anywhere.  We’re talking hotels, airports, book stores, etc.  I found out today that Boingo is adding service to Dulles and Ronald Reagan airports starting in a few weeks.  Handy.  Maybe WiFi roaming will start to displace other methods of access?
