Obviously, there is a multitude of systems already in place and extricating ourselves from this won't be easy and won't happen quickly. But rather than working to streamline these processes, representatives of content industries are spending a great deal of their time (and lobbying power) trying to do the impossible: stamp out piracy.
Agreed the piracy issue is a red herring; it's an emergent side-effect of the unavailability of cheap, convenient legal purchase options. But it's also one that is popular with the folks who fill boardroom seats at the top, who tend to be old and anxious about hot new technologies that they don't understand.
And that in turn is an emergent side-effect of the wave of media conglomeration that happened in the 1980s, as large publishers went on acquisition and merger sprees and ended up as part of huge groups within a handful of large cross-media multinationals.
What they urgently need is some sort of cross-licensing agreement, but I'm unsure where it's going to come from ...
