Moreover, there are widespread examples of colliding UUIDs, say EBD0A0A2-B9E5-4433-87C0-68B6B72699C7. This means that this idea have already proven to fail on it's intended usage. > ?There are lots of applications out there that use UUIDs pretty successfully. Much less than a number of applications which use integers ;-) Val. Dav.
