>"Oh, yeah we reuse the references after about 90 days... And, no, we don't have any globally unique references." The minute a simple unique identifier is established for something, someone who is just important enough not to be told "no" screws it up.

Sooner or later, they ask for a report that distinguishes between them, though.
