One technique that I use when I need different access permissions is to have
a setuid/setgid shell file which, after checking the real userid against
an access list, will exec a program which sets the real uid/gid to the 
effective uid/gid and execs its argument.  Using csh, this means that I can 
have multiple jobs running shells, each with different access permissions
(Of course, the setuid/gid shells must be set up in advance).
I can then just move between them as needed.  This method saves typing
in passwords (as with su) and having .logins, etc executed.
