<p>This document describes tools capable of managing digital content based on a user's identity. By so doing, the tools free people from the limitations of their storage media and devices. If a user's CD breaks or hard drive fails, the tools permit a user to continuing accessing his content. If a user wants to use a new device or even many new devices, even if those devices play content with a different format than a user's existing devices, the tools may permit him to play his content on those new devices. If a user wants to share content with a friend, the tools may permit it even if the user does not have the content on hand.</p> |
