The hardest problem I've seen people have with Google Glass is how obvious it is you are wearing the glasses. People in public assume you are recording them and it bothers them.
If you over come that, I think it would be a fantastic barrier to remove.
So, you have no issues with people recording you when you don't know about it?
You think is OK for some Glasshole to walk into a restaurant where you are enjoying a public yet private dinner with a friend, record it and put it up on the Intertubes? You are OK with that. I mean, it is a "public" place, right?
I know, public places and all, just posing the question...
