I sympathize with your frustration, Rich.
I can only offer some of my own insights, here.
The way it was explained to me is this, Acrobat has no inrerface for setting
rendering intents because they are set at the object level.
The only RI interface I know of is in the Color Management pane of the
Preferences. But this is probably not what you are looking for. AFAIK, this
RI only affect the "Output Intent", similar to PDF/X-1a.
The most frustrating is that Adobe has not deemed important to make any
changes or improvement in Acrobat 8 color management, compared to v7.

"Device" means "device dependent" (RGB, CMYK, Gray) whereas "Calibrated"
means it has some sort of "profiles" associated to the objects like CalRGB,
which is a kind of ColormatchRGB or idealized display profile.

Makes sense.

Beats me, Rich. I haven't given too much thought to this one.

I don't think there as such things as "device-dependent" profiles in PDF.
Device is just that, raw, uncalibrated data. And, I would suspect that
Device falls under the Output Intent. But that's pure speculation on my
part.
