So, how can two databases, not currently talking to one another, guarantee that their GUIDs don't collide? using a large randomly generated name space only reduces the chances of collision, it doesn't actually guarantee it.
Like MD5, there is no 100% guarantee, but the collision possibility supposed to be is very close to zero.
