I would be all over this if they had voice acted parts for the AP's that you could have the players listen to. I'll probably buy it just to find out, but changing it from a story to an asset that can be used when running the AP would be amazing. I have done this myself with a voice modulating software (mostly for beasties). I also play music, edit game ambient tracks and music to fit scenes.
How neat would it be to set the scene, describe an NPC and then play the voice acted part.
