[Heltzel, Dennis]  You would need to use ACL's (Access Control Lists) for
this kind of fine granularity security. I don't believe any Linux FS has
implemented these yet, so you are probably not going to be able to do it.
Non-ACL UNIX security has only 3 levels,
1) Owner - Single user, not a group
2) Group - Subset of all users, can have many members
3) All - Everyone on the system
