That was my thought as well.. no, it isn't instant gratification, but it does have value... I wonder how legal a dedicated feed rental system would be. Effectively, you rent a movie (as available) and someone puts it into a drive in a data center, that is then played for you directly, with the software interface controlling playback... you then click "return" when done watching... maybe a bonus for early returns (vs checked out for 24hrs).
It might take some custom hardware, but just a few larger central stores vs something like redbox for example.
