Owen,

Unless I'm misunderstanding, what's being asked for is a visualization 
tool for the *classification*.  Faceted browsing by subject is dandy, but 
is not at all the same thing (though arguments can be made that the lines 
are blurring).  Books that sit next to each other in a classification (DC 
or LC, or whatever) may not share a majority of subject terms.  That 
collocation via classification is yet another (and occasionally more 
useful) way of saying that this item is like that item.  One that is not 
necessarily trapped in any other way than call number.
