I read a bit about Dolby Volume in the coverage of this year's CES, and I agree that it could be handy. It would certainly need to be a user-selectable feature, of course, and selectable on a per-input basis (use it for cable, satellite, or broadcast TV but not for music sources and possibly not for DVD or Blu-ray/HD-DVD sources). As of CES2008, I think that it was running on a modified Onkyo receiver, so I don't know if anybody is yet offering it in production hardware, but if it were available for inclusion it would be cool to have...
