Nothing. I think that's correct. The only problem is broadcasting the keys is not simple. The latest systems change keys frequently-- as often as every 20 or 30 seconds I seem to remember. If you change the channel, you need a new key. It's not like the old days when the key changed daily or monthly. If you have such a service broadcasting the keys, it's not too hard to track you down. So I think it's not a practical solution. -Peter
