This is where Unix's all-or-nothing security model is a real pain.

One solution is `sudo', which allows you to specify that certain users
can run certain commands as root.  I think RedHat's PAM can do similar
things (but I really need to do some more reading on PAM).

Recently, I've been using `tcpclient' and `tcpserver' from the ucspi-tcp
package to run limited commands with extra privilege, even on remote
hosts.
