it can be implemented to prevent spying, etc. That was one thing in Second Life that people could do, use their click and zoom camera options to eavesdrop or spy on people from a distance. But other than that, I really liked that camera system for being able to exactly position my camera where I wanted it to have the view I wanted on screen. It would also be useful for those moments in desktop mode where things in worlds can be hard to see or read, to be able to click and zoom on it directly. I ran into that a lot in desktop mode in game worlds and such.
