Imagine it -- you're walking through an ancient Egyptian tomb, and you spot a small artifact on the ground. You bend over and pick it up, carrying it in your left hand. Further down the hall you encounter a fellow archaeologist examine a sarcophagus, but they can't see it in the dim light. You hand them your torch, and now they can see everything. That's exactly what you can do with two players in Real Virtuality, using your real hands, arms and feet. Check it out, it looks awesome!
