"she sent the same images to her roommate"

I think this use case is unfixable by software. You can aim at the same person perceiving the same color on different display devices, if that specific person calibrates all the devices (or selects the profiles). I doubt you could ever get two people to perceive the same RGB value on the same display as the same visual stimulation, and to capture it with the same words.

When I look at a piece of cloth simultaneously with my wife (real time, same place, no display device involved), we regularly call it different colors. You'd have to calibrate eyes and brains to get consensus.

I think this idea is blown way out of proportion. I mean, everyone go ahead if you feel you need color calibration, just don't foist yet another daemon on me. Give me an opt-out.

Eyes are already calibrated by the fact that we're extremely similar
genetically, and it's a very well known calibration:
<http://en.wikipedia.org/wiki/CIE_1931_color_space>.
There are certainly slight variations between observers, and known changes
as we age, but our person to person match is a whole lot better than two
random displays.

Color naming on the other hand has a large learned component, so yes,
people can disagree fairly widely on how they interpret and describe
what they see. There's been some interesting research on this, for
instance:
