Think about what a device like this would have on.....war, for example. Anyone could upload GPS and full video, at any time. Feed it to a site like YouTube or Reddit, and other users would 'vote up' the important stuff. If enough people thought it was important, the whole world could be watching one random guy's feed 30 seconds after he starts broadcasting, wherever they were and whatever they were doing. After thousands of years, we might finally have a chance against "Dulce et decorum est pro patria mori." It's the only thing I can think of that would, too.
