OK, so the important part here is that there is a separate font face set 
attached to every "node scope", right?

Have you examined the performance characteristics of this?  Font face 
sets do a bunch of caching, and it sounds like it will all need to be 
redone on a per-shadow-tree basis, so somewhere between "a few" and 
"hundreds" of times per page, no?
