Yes I can appreciate that, we have done the same thing im '500'...

oops....

As an educational setup we are looking to federate worldwide, that means 
Shibboleth or similar....a unique UID per academic world wide 
 might be worthwhile....there wont be 2billion academics...students...well i 
guess that would one day be a "ipv4" problem.

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.
