I was thinking about this, and it occurred to me-- if your drives don't
mind double-thickness disks, you could get a good deal of top-side
scratch resistance by gluing a dud disk to the top of a disk you want
to protect.  (Or you could use an unburnt blank, or for that matter a
mass-pressed cd, but it seems silly to not find a use for the coasters
I'm sure we all have around.)

Of course, you also need to find a glue that isn't going to wreck the
polycarbonate.  Any materials scientists here who know enough to
recommend (or disrecommend) any glues?
