CameraPick is designed to be used with the mouse in mind. Or for any other reason you'd need to choose the pick from a 2d location on the screen. Line pick is really for blind picking. When you want to find out if something is actually there.
For example, a platformer. You'd do a pick below the character to find out if he has something below his feet, but not yet touched the ground. Many uses :o)
