The "&" doesn't terminate anything.  It simply moves the process to the
background and leaves it attached to the parent process.  The parent
process cannot exit until all of its child processes exit.  What you are
looking for is this:

   start() {
             date >> /root/joe.log
             nohup /usr/bin/joevpn start &
             RES=$?
             return $RES
   }

The "nohup" command will detach the joevpn process from the parent and
allow the parent process to exit.
