I disagree that "remote mounted sudoers is bad" ... 

The NFS File Server should be exporting the sudoers file READ-ONLY
to the clients. So only folks with sudo/root access on the file server
itself can modify the sudoers file. And we actually have a SINGLE
sudoers file on ONE host that is rdisted out to those file-servers.

So if you don't "fully trust" a particular person/admin, then don't
give them access on either the file servers or the "master" server.
If you DID give them access, or at least enough to modify sudoers,
then you have inherently trusted them with the keys to the kingdom.
And if they did something against policy, then that is a non-technical 
problem and not a "fault" with sudo itself or remote mounting.

My two cents,
