[mythtv-users] limit daily tv time?

[David L]

Is there a mythtv setting to limit how much mythtv playback time for a
certain profile is allowed each day?  I want to limit my kids to like
an hour per day and it's hard to keep track of how much they watch
while different people are taking care of them during the day.  I
could just disable mythfrontend with a cron job, but I was hoping
there was a native mythtv feature that does what I want.

Thanks,
