I'm unconvinced. You have a lot more confidence in Congress' ability to take action than I do. Especially on a topic that pretty much guarantees that a public brouhaha would end badly for congress. I can see the complaints now:
"You nitpicked Google, but you approved the Patriot Act?"
It seems pretty clear to me that the government has no credibility from which to try to advocate privacy without first starting from within. And frankly, I think we need products like Google Glass to ensure that more unanticipated events can be caught on camera. Cops abusing their power, transactions with lying customer service reps, and I recently had wait-staff who probably could have used this, etc. These are more important topics than whether someone gets a picture of you in the gym locker room.
