locking a users file as root

hello,

I have a challenge to find a way to lock down a file in a user's home directory, such that a user can NOT modify, rename, move, delete, etc. The solution needs to be deployable without, for example, having to switch from unix to windows, etc

We are using NFS. We want to lock the .xscreensaver in the user's home dir and not all the user to modify this file at all. I chmod the file to 700, owned by root:root but the user can go to his home dir and still do whatever he wants with this file because he is the owner of the parent directory.
Any ideas?

thanks for your help,

how can an user modify a file that own by root??
You can write a little script to overwrite that file everynight. Eventually they will get tired of change it.
