One more question, If I create 3 vserver processes by this way, and I allow
the 3 processes can access only certain files in my machine, for example,
only 4 files on my systems.
Can I group the 3 processes and 4 files together? say, they can see each
other on their vserver domain, but they will not be accessible by other
program on my host machine?

Thanks,
Wenbin
