Another "way" to get the DOF you want, is to buy in TS-e lenses. Sure there are compromises, but so does stacking.
He's not after DoF, that is he's not taking shots at different focus points and combining them for large DoF, he want to take a series of shots at a range of different apertures to see which one works the best. You certainly don't bracket aperture when doing multiple shots for extended DoF.

Took the risk and loaded the Magic Lantern software, all went well. Problem is the DOF Bracketing feature is not there. It seems that feature is only on the NIGHTLY BUILDS software, which is USE AT OWN RISK they say....hmm.

Generally speaking the biggest risk from ML is in the first install, since it modifies the boot loader in your camera's firmware. Once you get past that the ML image itself is loaded off the card every time you turn your camera on, so if you encounter a bug its effects should be limited to that power-on session (provided the bug didn't corrupt one of the NVRAM properties), after which you can simply cycle power or if need be, remove your CF/SD card so that ML doesn't boot for the next power-on session (or leave the card in and hold "SET" down during power-up, which will bypass ML for that session). You can then decide to fall back and flash to an official ML release or even stock firmware.

Thanks for the clarification. That seems to be dfficult to obtain considering that the AF focus happens automatically - so in manual focus, one would have to rely in tweaking the focus point manually,and using a narrow DOF to start with - how can them the software guess where a given focus range will be?
Indeed the TS-e lenses wil not be automated, but will allow a superior control of DOF - without changing the aperture or speed settings - just a knob twist (or two). you can have a very narrow to a very large range,and withe the newer lens versions, that allow T&S rotation at 0 to 90 degrees, focus/DOF can become very creative.
There is a specialized stacking software - actually comes together with hardware, that allows automated focus stacking. The camera sits on rails, and a small electric coupled motor, does the work, per say. according to pre-set software comands. It's used in ultra macro photography.
Not sure if it fits the bill, but maybe can be adapted.

I do not need or want stacking, simply three images shot at three different apertures, all with one button press on the camera. It bewilders me why this is not a stock feature.

OK, varying aperture to control DOF makes sense, but I still don't understand why you would want to shoot at every full stop throughout the camera's range. Either you could just select the aperture that produces the effect you want, or you might shoot one at a very large aperture and one at a very small aperture.
What am I missing?

Dan, I shoot products for my web site, but I prefer a stylised shot at times rather than an 'all in focus' shot, but depending on what I am going for, I may like a shallow depth of field or a really shallow depth of field.
Some examples of the shooting I do is here: click here
The above are fairly standard, but when I want the varying depth, it is for a result such as the banner graphic on this page: click here
The above shot was taken three times at f4, f8 and f16, and I choose which I want to use later.......Show more →

It is a simple matter of having the ability to choose POST shooting and image processing, which depth of field suits my needs. I can not simply just use f8 as that is not what I always want, sometimes I do want to use the shot with f2.8, it all depends on the creative I am making at the time, which can be sometime down the track after shooting.
