Now this is just crystal-ball wishfull thinking, but envisage there 
would be a tool that works like this:
1. make a photograph (with lots of colours and contrast) with your 
camera without icc
2. print this photograph on your printer which also comes without icc
2. make a photograph of the resulting print under good lighting 
conditions (now, this is probably the weakest part, it would be better 
to scan it using a scanner that *does* have a colour profile)
3. - here comes the magic - run a program that analyses both photographs 
(or the photo and the scan) and automatically creates a colour profile 
combo for your printer and camera, such that at least any photograph 
from that camera that is printed by that printer will come out colour-true.

Of course your monitor is completely out of view for a tool like this. 
However, your printer would at least give a good preview for what a 
professional printer will give you.

This would of course even be easier if the printer is the only device 
without a proper icc profile, e.g. your camera and scanner both have an 
icc profile.

(This was inspired by the brilliant thing my cheapo inkjet 
printer/scanner combo does: to calibrate the printer heads position, it 
prints a special page which you have to put under the scanner, which 
reads it and calculates the proper calibration values from it.)
