Here's one that I think you forgot, Rob. There should be a 'remote finder' device that comes with the remote and that would be stored permanently next to the TV. Whenever your children lose the remote (at least several timess a day in our house), you should be able to push a button on the 'remote finder' and that should cause the remote to beep. (I presume you would have to use RF for this feature so that you are not limited by line of sight.)
