http://www.peertopatent.org/patent/27/prior_art/list Systems and methods are described for an off-line economy for digital media. In one implementation, exemplary media devices of buyer and seller participate in the off-line economy by performing secure off-line transfers of digital media content between themselves. The media devices store proof of the off-line sales transactions, so that a percentage of the sale price can be applied to a copyright owner and a percentage of the sale price can be applied to the seller as an incentive. Even resale of pirated media content benefits the copyright holder. The off-line economy opens an effective and inexpensive distribution channel for copyright holders and allows buyers to obtain media content anywhere, at any time, from any participant in the off-line economy without connecting to the Internet. The off-line economy allows copyright holders and media sellers to optimize pricing by market probing. en-us Off-line economies for digital media Patent/Application #: US4789863<br/>Description: In this pay per view entertainment system, recorded entertainment (musical works) are distributed to subscribers over a cable network.

Also, the methods described are immediately and obviously applicable to &quot;offline&quot; transactions in the definition of the application. (The first and second devices in fact form a network between each other for the duration of each communication transfer, so &quot;offline&quot; is with respect to the parts of the described method that are not the two devices, making the distinction irrelevant in this comparison.)
