Thanks for getting back to me, David. I'm going to sound
argumentative here not because I'm disagreeing with you,
just because I'm trying to understand where there's a flaw
in my logic; I hope you'll take it in the manner intended...
No, it was me that started sounding argumentative (I'm in the aftermath of a major icestorm, no electricity at home, up all night feeding the woodstove, etc... ). But I really can't teach an entire course in color management theory via email for an interested programmer, so I will decline to answer your long list of theoretical questions here. Sorry. Reading the ICC spec, and attempting to learn color management from first principles is an admirable thing, its just unrelated to end user usage of commercial color management programs. Besides, if I attempt to answer your questions here, it will only create a second, then a third generation of theoretical questions.
Let me give you a couple hints: display profiles do not use rendering intents, that is restricted to output profiles. And one more: data going to displays from Mac or Windows videocards is eight bit per channel, so there is no magic way to make adjustments without levels losses except in the display.
