I meant the user can choose the intent that goes between each profile  
in our UI. They can choose the intent that comes after the input  
profile, after the printer profile, and after the proofer profile.

Since cmsCreateMultiprofileTransform doesn't provide a place to  
provide these intents, I assumed lcms would use the intent currently  
set in each profile at each step. When the user sets the intent in the  
UI, we set that intent in the profile object.

Yes, I need the monitor profile because I'm color matching to the  
screen, as stated in my original message. This might be "soft proofing".

Can you explain why the printer profile would be given twice? Would  
the proofer profile also need to be given twice? E.g. input->printer- 
 >printer->proofer->proofer->monitor?
