Higher resolution image capture for applications dealing with face recognition would be awesome. Is the team holding off on face recognition until a higher resolution camera/kinect is in place?
That said, you COULD go the way of several hacks I've seen - marry a high resolution external camera to the Kinect rig, do the correspondence, and use the external camera as your face recognition input.
that said, we do enable you to use the infrared feed and marry that to a hi-res external color camera.
Your sdk is slow moving and limited for all the resources that your empire has at it's disposal.
Do note, that the SEC report the last I checked, included the biggest competitors as Linux and the GPL. The last they'd give is source for the free masses to use.
