heh, I heard a little bit about this before, and today I read This. Basically up here in Canada they are considering making it against the law to be on a Cell phone while driving (unless it's an emergency), AND they're considering allowing Cellphone jammers to be sold for restaurants and concert hall type places. In other words, they can block it, if they feel that they are inappropriate.
Personally, I'd have to agree, I don't think they'd be appropriate in certain situations, especially in Cars. The argument against is that in case of an emergency if you are within the area of jamming effect, you could have problems (though I could think of a few solutions to that problem).
also, an interesting fact near the bottom of the article. Currently there are 8.3 million cell phone users in Canada, that's out of about 30 million people or so, which means the percentage of Cell Phone users is high.. it's odd that a fair amount of people in my school have cell phones too (though so far I've never been in a class where one went off).
