comment from Mike Schwartz:
umm, I think there may be a way to do  this with
access control lists.
If an ignorant lurker may insert his 0.02
The problem with groups, as I understand it, is that
if you want a person to be able to be a member of
several of them,
(especially if the groups are not monotonically nested),
then a given person might have to have "more than
one" userid (not a cool solution...);
Whereas with an acl, I think there is much more
flexibility.  I have used ACLs before under VAX/VMS,
but for Gnu/Linux, I do not know the details.
However:
The textbook being used for CIS238DL at GCC
this semester (a Linux class taught by  "Ray
Esparza" <ray.esparza at gcmail.maricopa.edu>)
(Sobell, Mark G., A Practial Guide to Red Hat
  Linux, 2nd ed., Prentice-Hall PTR, 2005)
(ISBN 0131470248)
says on page 927 to see the acl man page
for more information.  It also says that ACLs  are
part of Solaris, Win 2000/XP,  VAX/VMS, and
mainframe OSs, and that they are available
under Fedora Core 2
(so presumably Fedora Core 2 "and later").
I hope this helps.
