Redbox for travelers at the airport is what it sounds like to me. I found this thing called Digiboo. If you are bored and dont have internet connection to download a movie while waiting at the airport they have these machines where you go plug in your usb and download a movie right onto it. It is only in like 4 states right now but it sounds like a good idea. I haven't tried it yet but I'm going to next time I'm at SeaTac.
