Multiple Cameras

What I want to be able to do is have essentially two screens in my game, a main screen, and a "strategic screen" that shows the whole map, which will be zoomed out and represent the game objects as icons. I thought I could do this would two torque cameras as in the split screen demo, but I don't know if there is a way to represent a given game object differently in different cameras. The only solution I can think of is to write my own camera and use that. Any suggestions on how I might make this easier, or if there is a way to do this with torque?
