Many, many organizations start with the same uid base, 500 or 1000. When 
company A buys company B there are tons and tons of uid collisions. If 
each started at a random start point then the chances of collision, 
while not zero, are much lower.

Our goal wasn't to guarantee uniqueness in the universe, just to make 
integration hopefully easier in the future when namespaces are merged.
