Ross Mayfield on a Lufthansa flight and Jeff Nolan on the ground share their banter. Thomas Otter adds in the comments that once he got on the WI-FI network on the plane he used Sykpe to call someone. We may soon be able to use our cell phones - though many are ambivalent about that.
I have an idea for Bose - develop a mouthpiece that routes voice to a USB port on a laptop or to a cell phone, but cancels out the voice to rest of world...or plane in this case.
Then if we could also put on white paint, like Marcel Marceau we could also provide the flight entertainment....
