Two questions cansouth,

If this satellite technology can be used to make people touch their faces more often, without any fancy reciever equivment, why can't it be used to stop them smoking, or send all their money to the hacker, or something?

Are there any laws governing what can be broadcast from satellites? I know there are national laws governing what you can broadcast to a country, but are there international ones? It doesn't seem to be promoting anything like terrorism, drugs, pornography etc, so is it actually illegal?
