Thanks Kevin.

For the benefit of the archives, here's how I did this:-

1) I added a menu item called "Restart Backend" according to this: 
http://www.myhdbox.com/mythtips/2006/04/tip-2-how-to-customize-mythtvs-menus.php. 
I added it to the Utilities menu.

   <button>
   <type>SHUTDOWN</type>
   <text>Restart Backend</text>
   <action>EXEC ssh -l mythtv server.home "sudo 
./restart_backend.sh"</action>
   </button>

2) I set up RSA keys for the mythtv user, so that it can ssh into the 
backend without having to enter a password. On Gentoo, this is made 
easier with ssh-installkeys, discussed here: 
http://gentoo-wiki.com/SECURITY_SSH_without_a_password.

3) I created the "restart_backend.sh" script to restart the backend, and 
added the mythtv user to the sudoers file, allowing it to run that 
script without a password:

   mythtv ALL = NOPASSWD: /home/mythtv/restart_backend.sh

and that's about it.

Cheers,

Jon
