Scott,

Yes it's great isn't it. The 350D already has excellent low dark noise.

Bert, try mounting a 12 V 0.5A fan near your 5D and blasting it with air. It definitely helps reduce dark noise.

I don't think SBIG/Apogee/Fli-Cam type people have too much to worry about though. If you look at the specs on some of the new Kodak sensors they are very impressive. The KAF-9000 CCD use in the Apogee U9000 for example has a 38 x 38mm square sensor area, 3k x 3k pixels, 7e- readout noise, 70% peak Quantum efficiency, 5e-/pixel/sec dark current at 25 C. That Quantum efficiency is achieved with antiblooming control!
