Yes, it's too bad that the Canon flashes don't use the lens distance calculations. They could work on a simple internally calculated aperture based on the guide number. Then you wouldn't have to worry about the reflectivity of your subject at all.
Nikon apparently has a patent on this with their 3D metering. :-( We just have to wait another 10 years or so until the patent expires.
