I didn't mean a serial number, but something more along the lines of a
lot number, as the stampers apparently wear out fairly quickly.
Something that would make the odds very poor that you'd get an
identical disc.

However, looking at the wikipedia article on compact disc
manufacturing it doesn't look like there's an easy way to alter
mothers or stampers to implement that.
