Huge response, thanks folks.
The answer is that you can use netgroups throughout /etc/exports EXCEPT with
the -root option. And -root is limited to eight hosts.
The workaround suggested is to designated a few "trusted" machines and put
these in the -root option on all machines. If you want to do root stuff,
you do it from there.
Thanks again for the overwhelming (and consistent) response.
