Sound Proof Barrier in the Mini-Van

After traveling way too far in the last 5 days via mini-van I think the market for this particular product is huge.  It would simply be a sound proof, see-through barrier that would separate the driver and passenger from the chaos of the back seats.  I also suggest a simple padded, portable, institution like room as the back chamber of the mini-van.  Throw a couple fruit snack packages in there every few hours and you've got yourself a family road trip.
