On my machine (an 040 Cube/660/OD) I name all my Opticals /Optical. In
my /etc/exports file there is a line which reads

/Optical -access=daffy,root=daffy

When my machine boots, it finds that there is no /Optical, and therefore
does not export it. Even if I then insert a disk, the user at daffy
cannot mount it, unless I first su to root, and issue an exportfs -a 
command.

And even then, only the machine "daffy" has access to it. Since the
manager of daffy is my business partner, and daffy sits five feet
from my machine (bugs), we don't have a problem.

Granted, we frequently run into the ownership problem, but we usually
only use the Optical for archival purposes, in which case we both log
in as the same user (member or operator and wheel). 

In short, I see how it could be a security risk. But like any risks,
if you're careful, you'll probably be fine. Just keep those ODs out
of strange hands.
