Given your description nobody was aware that they were being recorded.
Well, yeah, that's kind of the point - emulate what we've seen of google glass as much as possible (and also be useful when watching morons drive). I made sure to be well aware of the local surveillance rules and all of that, clients are told about the glasses and the possibilities, people are so excited about GG technology that they're not stopping to consider the ramifications. Pretty much anyone who posts on here has thought about them (as is evidenced by the attempted testosterone flowing from some of the other comments) but they're not the general public.
However take those glasses into the gents or a changing room and I'll not be happy: context is the key.
All I see in the news lately is how good Glass is, with lots of comments about the need to be looking directly at the person to take a picture. The public are being calmed before the storm.

My old boss always cheated - pull a drive from the RAID-1, take it home while the RAID-1 rebuilds with a third drive. That way one is always offsite, and the work is always saved on two drives.
Fortunately (or unfortunately depending how you look at it) he's never had a disk fail mid way through the daily/ weekly rebuild.
