A method of securely packaging multi-media content is provided. The multi-media content is to be rendered through a corresponding rendering application. The application limits rendering of content according to sets of usage rights associated with the content. The application further provides or facilitates a communications medium through which a user can negotiate with a remote server for additional usage rights. The method includes: i) receiving multi-media content to be securely packaged; ii) receiving an identifier for the content, the identifier helping to identify the content during a negotiation for additional usage rights; iii) receiving a first set of usage rights, the first set of usage rights identifying a minimum set of uses of the multi-media content that are permissible without requiring a second and expanded set of usage rights; and iv) packaging the multi-media content, identifier and first set of usage rights in a secure container. Despite being packaged in the secure container, the multi-media content remains accessible for rendering by the application for up to the minimum set of uses as established by the first set of usage rights.
