So um, that means using it to produce a UUID is ok as long as I'm willing to accept the odds of a clash (very unlikely). I've more chance of being hit by a bus than having to deal with the consequences of a little ID clash in my system. Therefore I should focus my energies on watching out for buses than coding around clashes of IDs. Maybe I should go to bed ! Brett.
