Et phone plane

I've used Skyphone a few times on BA, and its a cool little service, why not have a service for Earth to call you up in the sky.

This would also be done by using satellelite connectivity. One would go online and through a database of Plane phone numbers, would search for the one they want to call. A switchboard on the flight would redirect them to the person they wish to talk to, after quoting their name and seat number, which the passanger would give to people they're expecting calls from prior to the flight.

I cant particularly see why this would be important for me right now, but I'm sure a lot of people out there would appreciate this service.
