I wonder, in the event that this support is activated, if the 2 DRC will be able to communicate directly with each other, or any interaction between the two must pass through the system before, and if it's the latter case, there won't be any noticeable latency problem, etc.
Here's another idea, applied to a sport setting, like baseball.
Player 1 must throw the ball with movements on its controller touchscreen (like the shuriken E3 2011 demo).
Player 2, on the other DRC, can visualize in 3D the ball coming directly in its direction, and must catch it while holding the controller, arms stretched, in front of him (like the shield pose demo).
It could be used for a lot of contexts, imagine a virtual war in your living room, combining the motion control capabilities of the padlet + its own screen as a "window" allowing to peer into the virtual world, one throw grenades or other weapons while the other protect himself by triggering a directional energetic barrier, etc.
