    dynamically providing a second special purpose renderer that is specific to the second instance of encumbered digital media, the second special purpose renderer for unencumbering and rendering the second instance of encumbered digital media and the second renderer being a product of the first renderer operating on the first instance of encumbered digital media, wherein the second instance of encumbered digital media and the second renderer are dynamically generated as part of the same operation;

    a set of digital rights management controls integrated into the first special purpose renderer, the set of digital rights management controls enforcing pre-designed policies controlling access to the first encumbered digital media; and
