Imagine if when you obtained a book (or a song or a movie), you could know whether or not the way you obtained it was explicitly endorsed by its author. Could you use that information to make better choices?
I think so. Here's a scenario: you walk into your local copy shop and ask for a book you saw recommended on someone's blog. Machines to print books on demand are already here (see the Bookmobile, for example), so let's assume that printing up a book at a copy shop is a reasonable thing to do.
Under the current copyright system, the copy shop must have permission from the copyright holder to print the book for you. One way for them to get permission is to work out bulk deals with publishers, so that every time the shop prints a book, a certain percentage goes to the publisher (and then a percentage of that goes to the author). Another possibility is for copy shops to become publishers themselves, bypassing the traditional publishers and working out deals with authors directly.
