The 1DMIII and the D3 both have settings that allow you to choose min and max for:
shutter speed
aperture
ISO
In a studio where the lights were under your control, I can see why it would not be useful, but imagine shooting sports under variable lighting (clouds coming and going).
You want at least 1/500 for stopping the action and a fairly large aperture (say f4) for isolating your subject. Set the camera on M, 1/500, f5.6, and auto-ISO with a max ISO of 3200 and a min ISO of 50.
Both the D3 and 1DMIII product very nice images at ISO 3200.
Ummmm - I can imagine it - I shoot sports all the time.... even in a broken cloud situation I can't see the need for an autoISO - heck, even using aperture priority has its risks due to the situation of moving from backlight to frontlight over the course of a single play... Besides, in your situation, I'd rather set the ISO and aperture to where the darkest cloud gives me the minimum shutter speed then use Aperture Priority to allow the shutter speed to rise above that when the light allows.
The only single use I could see is for an twilight game which starts in daylight and ends under the lights - during that transition period I usually check/adjust exposure every 5-10 minutes... Not particularly difficult to do manually, and I would still need to turn off the autoISO when the daylight became dark enough that the stadium lights became the primary light source...
Like I said, I just don't see using it much...
Just my .02
