Maybe you could reconsider this, as the Leap Motion would be the perfect standardized tool for tracking infrared LEDs, for instance for 3D head tracking (not only VR-glasses like Oculus Rift).
You already offer the possibility to track a pencil, but tracking IR LEDs in 3D would provide developers with lots of extra possibilities and probably more stable tracking of custom made tools.
For starters, disabling the LM IR leds would be a big leap (pun intended )
