I think one of the better uses of this camera will be in law enforcement. Not only can the glass record everything that happens, cops can use it as a tool to aid in real-time communication, a win for civil liberties groups as well as cops. Ensuring that the video evidence can't be tampered with or deleted is critical.
Actually, last night, I spotted some BART cops with glasses that had a little camera on the side. Pretty sure that they didn't have screens but it brought a smile to my face. Definitely a step in the right direction.
