Now the sensor appears to deliver 640x480 again, which might or might
not be just blown up 320x240on the onboard ASIC.

That=B4s really the interesting question, along with others like how to
calibrate visual and depth image to get real RGB-D data. With the
current state of affairs one can generate some impressive looking
images, but to leverage the full potential of the sensor these
calibration questions really have to be solved.

That=B4s more stuff that will probably be discovered in the coming
days/weeks. Still very impressive how good the sensor works already
right out of the box.
