Abstract
A wireless broadcast of an electronic work with digital rights rules is received from a primary player at a secondary player. Synchronous play of the electronic work at the secondary player is enabled while the secondary player is within reception range of the primary player. A sample of the streamed electronic work with digital rights rules is stored at the secondary player. Responsive to detecting that the secondary player has moved outside reception range of the primary player, the secondary player only allows playback of the stored electronic work according to the digital rights rules.
