Not wanting to hijack this (interesting) thread, but ..

I have to concur with Rick P - that's rather a odd requirement when each 
FreeBSD install since at least 2.2 has come with root and toor (in that 
order) in /etc/passwd.  I don't use toor, but often enough read about 
folks who do, and don't recall it ever being an issue with NFSv3.  Are 
you sure this is a problem that cannot be coded around in NFSv4?

cheers, Ian
