An improved system, device and method for accessing features of digital products with assistance from a content distribution system are disclosed. Third-party content can be submitted to and distributed by the content distribution system. In other words, the third-party content can be hosted (and distributed) by the content distribution system. A download interface can facilitate application programs operating on a client device to locally request and receive downloads from the content distribution system. Typically, a user of a client device would purchase an application program and then sometime later, using the application program, also purchase supplemental content for use with the application program. Once the supplemental content is purchased, it needs to be downloaded to the client device. Download policies are used to manage the download of supplemental content.
