well apparently this crack works for Windows Media DRM for Windows Media Player 9, 10, 11 and Zune.. basically everything. a forced firmware upgrade would be possible on the Zune device, but MS will have to re-do all of their software, re-encrypt all of their music, etc.. with a completely re-designed DRM solution which probably isnt going to be very easy considering the crackers have really got that current DRM under control right now.
