Putting system accounts at high UID numbers seems like a common solution 
to me.  If we could reach a consensus on this I would be happy to make 
the required changes to my package (adduser).

If consensus can't be reached, perhaps I could just make it 
configurable.  We would still need to agree on a default config though.
