Would love to know how the technology works in the USA model?
Essentially they've built a big 3G mobile network and pointed it at the sky instead of the ground. Presumably the bulk of it would be on existing towers, and due to the lack of terrain issues you can space them out more. There's an antenna on the bottom of the aircraft and systems onboard that then make that data available over wifi.
I'm surprised it hasn't happen here, if only on the Mel/SYD/BNE/ADL routes. They'd probably need to get virgin and qantas onboard for it to be viable but it may never happen because flights on those segments are too short for people to really demand it, and extending it across to Perth is too hard.
