Hmm not a bad idea. or may somebody could just maybe you know, pay the $100, rehash it and sell the summary/rehash of the book for $20? Even different translations of it.

On a more general note, I wonder if a group effort/initiative exists to "open source" the rewrite of contents of these unbeleivably expensive text books? While content can be copyrighted, the re-explained content versions of these cannot be right?
