The only half-way reasonable idea I can come up with is to create a table with a finite pool of IDs and as they are used remove them from that table. Those keys can be unique and a script could be created to generate that table. Then you could pull one of those keys by generating a random select from the available keys. I said 'half-way' reasonable and honestly that was being way to generous, but it beats randomly generating keys until you create a unique one I suppose.
