You can tell this was invented and pitched before the studio DRM requirements were fully realised. Impulse buy a movie straight onto a memory stick at the airport, great idea. Introduce an element of DRM with online activation, and you instantly lose customers and create a sizeable customer support issue.
In fact even without the DRM, would it not be more convenient to do this by integrating it with the terminal wifi? Add some NAS storage and a web shopfront to the access points frontpage, and flyers could purchase and download whilst sat waiting to board.
