mounting nfs partition depending on user

NFS Newbie alert!!

I want to mount an nfs partition based on who is logged on.

In other words, I want to restrict who can mount a partition.

I have two sets of users: kids and parents. I have movies that only the
parents can watch.

The movies are accessed via a browser. Anyone can watch a "kid" movie;
these are mounted at boot time. There is a default index.html in the
"parent" movie directories that simply puts up a message that you have to
be logged in as a parent.

If a parent logs in, the "parent" movies are mounted via NFS, the default
index.html is no longer visible and the index.html on the mounted
partition shows the movies that are available.

I want all this to happen automatically. So, how do I mount an nfs
partition based on user? I know that I can put it in ~/.bashrc or
something, but I want to restrict *who* can mount that partition.

The little bit of reading I've done seems to indicate that I can allow any
user to mount a partition by specifying "user" but I can't say
"group=parents" or "users=a,b,c" or something like that. I don't want any
user to mount a partition, I want only users x and y, or who belong to
group z, to mount that partition.
