Well, besides my implementation of a Media Center PC, I do believe different source volumes would be a great addition. I am a little tired of turning the volume down to 25 for radio after watching a DVD at 45-50 and then going back down to 35 for TV/satellite watching. I don't think it would be that hard to implement a volume level per source selected.

Now, for those of you who do not believe that a PC implementation can be easily achieved, because of storage requirements. I predict by summer, or at least easily by year end you can get 2 TBs for under $500 and 3 TBs for not much more. So all of your storage requirements will be met to hold your exorbitant multiplicity within the 1000s of DVDs from the porn market you own. Oh, and I guess a few regular movies and CDs can be taken care of as well.
