Systems and methodologies are provided for a Digital Rights Management (DRM) that permits a service provider implementing DRM (the Service), to distribute and use digital contents to a plurality of devices designated by a user, via employing a registration component and a DRM component. The registration component can associate a user with a particular device among the plurality of devices, and also associate the device with its DRM challenge. The DRM component can issue licenses for content(s) used on the particular device. Such an arrangement facilitates users' ability to roam and use a digital content purchased across a number of devices designated by the user and approved by the Service. |
