Free international calls?

Via David Pogue in the NYTimes, news of a company called Futurephone that allows users to dial a domestic number and use it as a gateway to dial over 50 international countries for free. Many people can dial domestically for free in the evenings or on weekends via their cell carrier, so this is a sweet deal.

Will it last? I doubt it. But when the occasional crazy company comes along and burns cash in an effort to buy market share or build brand recognition, don't ask questions, just join the looters on the street and grab as much as you can carry.
