I just expect the OS to handle it. The problem with apps having to do  
something special to make it work is that so few developers do.

Apples own apps have only recently started to do color management for  
one display let alone two. So the dual support for dual displays at OS  
level appears to be tricky or not there until Snow Leopard. And in  
Snow Leopard the results are not elegant or particulaly good Ux.
