One other question for the group: has anyone out there torture-tested a
recordable-CD diskette after it's been written?  Someone recently pointed out
that they lack the layer of varnish that protects commercial CD's.  Has anyone
left one out in the sun, or shown a laser at one, or stomped on one/scratched
one to see how well the data survive?
