Perhaps it would be nice to extend MythThemedMenu[Private] to allow
requiring a password to select a menu item.  Currently we do this for
the setup page, but it could be easily modified or extended to work for
any menu item.  Jumppoints would have to be handled a little differently
if you use those, but there is already an editor for those, so
extending that code isn't a huge task either.

Want to keep the kids from destroying your heavily tweaked recording
priorities or even worse deleting a recording, just set a pin on that
menu item.  Until we get true multi-user and permissions this could be
an easy interim solution.

A table with the action name and a pin code would be easy to implement.
The list of callbacks from mythfrontend/main.cpp in TVMenuCallback
would be valid actions.  So if you want to deny access to LiveTV, you'd
just set pins on 'tv_watch_live', and 'tv_watch_live_epg'.

My daughter is now old enough to walk across the living room now and
grab the remote, so whether it's something like this or a hack, I imagine
that I'll be wanting something like this in the near future.  :)
