If you absolutely need for nodes to be isolated on their own media, why aren't 
they in their own individual domains which point to their own storage pools,  
all of which might share a library? 

Frankly, I like that TSM will override collocation preferences when its at 
MAXSCR for volumes in a pool. 

Just a thought,
