They had a hacky demo of this at the Leap booth at Unite in Seattle last week. The Leap Motion was taped to the front of the Oculus, and you could (sort of) interact with a floating sphere. It's a neat idea, but the tech has a long way to go if that demo was anything to go by.
I am excited for the advancement of input relating to VR though.
