I'm in the sudo camp on that, myself, but someone here said recently 
they write a user runnable mount program in C to do that. But if you 
are interested in sudo:

     man sudo
     man sudoers

If you are interested in writing a program in C, you should be able to 
find the guy who preferred that approach in the archives. I'm pretty 
sure it was in September, but might have been August. He might be able 
to help you.
