Whoa. Intelligence in keys is not a good thing. I'm not sure if I've heard of a good reason yet for a primary key to have intelligence. Even if users need something that makes sense to them, just add an attribute with intelligence in it and let them query that, but always have the primary keys and RI be based on random integers.
