[mythtv-users] Autostart frontend ONLY on manual startup?

Someone gave me their script which uses the following logic.

- Start mythfront/back ends every time the box boots up.
- At the same time as mythfrontend starts, start up irw in a script
which redirects its stdout to a log file and waits for 10 minutes
- When 10 minutes is up, check to see if the irw log file is empty. 
- If its not empty exit the script and do nothing
- If it is empty then assume that there is nobody using mythtv
(otherwise they would have pressed at least 1 button on the remote),
kill mythfrontend and exit the script.
- Now that mythfrontend is shut down the machine can go into its
auto-shutdown routine whenever it's ready.

I can send you the script if you want it.
