Nope.  You've never operated a device via reflection?  It's pretty fun when it works.  Roll away from the TV, point the remote at the wall behind you and things turn off.  The challenge are getting the angle right and if something absorbs the signal.

However, considering that the IR emitter on Kinect is significantly more powerful than a remote control, I believe it's able to flood the room with the light and ensure something will reflect the signal back into the device.

My guess is that it works pretty well, otherwise that wouldn't be even considered as an option.

Considering I have yet to find any device that uses an IR Blaster that doesn't directly point at the device they want to control, I think this will fail for most people that don't have the optimum room configuration.

My house as an example has a large front room that opens up to a casual dining space. There is no wall directly behind my couch that faces the TV/ent center. Granted, I know I don't have to have WiiU Gamepad pointed directly at TV for its TV/Cable/Sat functions to work. (Too bad it didn't work other devices too and it would be the perfect universal remote)
