I didn't actually play with such an app on google glass; but I imagine instructional content would be pretty good. For instance when repairing something, cooking/baking etc. I would love to be able to watch some tig welding video; drop the hood down and practice, then rewatch --without having to go back to the laptop or phone. First person perspective photos and video are, IMHO, much better than the phone - but its somewhat of a lateral move from existing head mounted action cameras.
