I talked with some people at UC Santa Cruz recently, and they modified the 
CAP software (aufs) so that if a file's Unix permission is "--x", then the
"bozo" bit is set automatically in its data resource.   I'm not sure how
this provided copy-protection (as I didn't get into the details), but they
seemed pretty sure that it was reliable.

The person to talk to is Evan Schaffer (evan@ssyx.ucsc.edu).
