do you realize that redhat uses checksums or signatures to check the validity of their CD's? try to burn a redhat image with the -pad option which adds a chunk of 0's to the end of the image and try to boot it. I seriously doubt if redhat tells you how to how to generate such a checksum/signature. in addition to the problem that Linus points out about being unable to change the contents of the write-only CD this would seem to conflict with what you are claiming the GPL is supposed to allow.
