I don't think the mouse wheel should be used for moving anything. Both within Blender (zooming/panning etc) and in other programs (scrolling), the mouse wheel is used for navigation. It doesn't perform any sort of function, rather it is just used to show you a different view of what you're working on. Using the mouse wheel to move things breaks this conceptual structure and causes confusion. You need consistency so the interface lives up to the users' expectations - if for example the mouse wheel is used for all sorts of different things then it's much harder for the user to predict what will happen, and it gives the impression of a 'black box' interface, rather than one that's transparent and easy to understand.
