The upcoming FPS game Reflex (I backed it as an early release on Steam) is excellent at doing just that. It allows multiple players to edit a map in real-time collaboratively. A very cool feature! In GameGuru I could see this as a possibility as you can already edit your own map while playing it in first person view--so that functionality would have to carry over to the multiplayer mode and then the changes would have to syncronize within the map editor once exited. Probably a lot of work by the developers but is awesome if done right. Here's a video (Skip to about
