MS Patents Offline Economies for Digital Mediamorlock_man writes "Microsoft has patented a novel platform for building off-line markets for digital content. The key technology enables an arbitrary user of specific digital content to resell their purchased media to other users in an off-line P2P manner so that part of the proceeds goes to content's copyright holder. More importantly, one part of the revenues is retained by the seller as an incentive for participating in the distributed economy. (United States Patent 20070136608)"
