Trent Reznor has had a wonderful relationship with Id software... It really doesn't surprise me, NIN did some fx and the sound track to Quake. I think it was kick ass for what they did for Quake, for sure it cna be done for Doom 3. If you've seen many of the NIN videos, you see they are very creative and weird, they can do freaky stuff! Once things go well for Doom 3, then shall the continuing process of Quake 4... Ty jonconley for da quote. So people speak it, we know you can wait!
