That's called "Little Brother"; we (for various forms of "we") have talked about it a lot.
Heh. Kinda funny. I called it "Little Sister" when I mentioned it to my buddy. Yeah, those are good points you make. A voting system that could downvote/purge irrelevant/private clips would be good. It should be motion captured, to preserve storage/bandwidth. Of course you're right that there are implications for misuse. I'm not sure thats a deal-breaker for me, exactly, criminal types will use their own tech to case a joint anyhow. Sure, maybe it lowers the bar, but there seem to be adequate payoffs. My main concern is the privacy implications, and the social implications, of people who get accustomed to always being on cam. I see it evolving to a type of super-amped up example of the Japanese concepts of honne (true sound)/ tatemae (facade). Honne being "how one truly is" and tatemae "how one presents themself in society." All cultures have such concepts, but for the Japanese, they were, and are, very deeply ingrained and felt, including nuance for different levels, and things one never says even to their closest associates. I don't know that those are trades I'm willing to make. The black bloc tactic of smashing cameras isn't bad, except like most of their tactics, it just won't scale. It's great for young adults with plenty of piss and vinegar in their veins, but its not going to attract the masses. I'm not worried about attracting the anarchist kids willing to get facial ink to make sure they can't get a proper job and "sell out" or willing to do a stint in the clink. They're going to be alright. I'm more concerned with getting to the critical mass of mainstream folks. Your points about providing a free type of security monitoring solution for their homes might help attract them, with the side-benefits being that it can undermine a state monopoly on surveillance. Still.. the social costs scare me. But those costs may very well get paid whether an open system exists, or not.
