 Well, I'm not 100% sure what you're asking, but there might be a good way.
When someone logs into a Unix system, the /etc/passwd file is parsed, and
last field specifies the shell to start up when they log in. For example,
if you want a 'virtual' user on your system - a user for a particular
process to run as, but not one that anyone could log in as - you can set the
shell to "/bin/false".

 Using this, you might be able to specify a small shell script that lets
them set up the ssh forward, and nothing more...

 Sincerely,

    How to fix your Windows Application when it doesn't work:
     (1) Stop and start the program
      (2) Log in and log out again
       (3) Reboot the machine
        (4) Reinstall the application again
         (5) Reinstall the operating system
          (6) Dance naked around the machine, waving a rubber chicken
           (7) "Take your machine back for servicing"
