Hi Steve,

To answer your original question, "no".  There is no interactive 
keyhole or split-screen tool.  Isaiah's suggetion (color blending) 
is the best available for interactive use.  

If you go that route, my further suggestion is to change compositing from
"Alpha blend" to "Add", and change the lookup tables to "Warm shade" 
and "Cool shade".  You may need to adjust window, level, and threshold.

-Greg
