You could use the built in locking in mythshutdown to prevent the 
backend shutting down. In your frontend-start-script call 'mythshutdown 
--lock' and when your system shuts down call 'mythshutdown --unlock'. 
You wouldn't need the wrapper around mythshutdown --check  or the 
touch-file then. You could manually toggle the lock from the mythwelcome 
interface if you want (press MENU then Un/Lock Shutdown or pressing the 
'0' key will also toggle the lock state. Not sure it is exactly what you 
want but at least you can choose if you want your system to shutdown 
simply by using the remote from the mythwelcome interface.
