A few months back we wrote a piece for Wired magazine about Voice over WiFi, and the potential for creating a wireless phone system on the cheap. Now Dartmouth College, which already has a campuswide WiFi network, is giving students Voice over WiFi software and seven-digit phone numbers so that they can make (and receive) free local and long-distance calls from anywhere on campus using a laptop and a headset (local and long distance calls were already free using a landline). Even more exciting, there are plans to offer Voice over WiFi software so that calls can be made using a Palm or a Pocket PC.
