Mirrors VR Robotics (Score 1)

I'm wondering if this could eventually be extended to people using their brains and nervous systems to control a robotic limb. Ridiculous expense aside, I'd think it would meet the "fools your brain into believing the limb is really there"-criteria that the mirror trick or this VR thing already fulfills, but with the added bonus of not having to lose the illusion when you take your hand out of the mirror box or turn off the VR.
