I get that your post was about Google Glass, and rightfully so. But isn't Google Glass just a part of the times? I mean, if I walk through a busy city, I probably am being recorded a lot. And no, people don't have cameras on their glasses yet, but cameras are still everywhere. I'm sure there are guys already snapping pictures of girls tits, without their knowledge. Its the whole "creepshot" thing that was going on in Reddit not too long ago. And lets face it, these people were not breaking the law, they were just being creepy. Out in public? at a restaurant? Bar? On the street? You can and will be recorded. Thats the reality of the world we are in. I don't think Google Glasses will have as big an impact as you think. Personally, I have a gf and one of my friends sent me a pic like you suggest, I'd message him back or whatever and let him know that thats not ok, and creepy to boot. Basically, because the option is there, you just have to know when and how to filter yourself. Gotta ask yourself, would I like my photo to be taken right now? likely not. Comes down to human decency. I like to believe that most people are decent.
