I concur. If we're going to allow users access to burn CDs, it's
impossible to police them with certainty as this case indicates. If we
allow vendor specific commands down, there are bound to be some that
format the drive or destroy the firmware ...
So I think ripping the table out and acknowledging we have no security
is better than giving the illusion of having it.
