I don't remember the details about Java 3D, but I'm assuming it will 
need an update to expose the tfp extension, so maybe they could roll the 
include inferiors bits into that too.

Yeah, that's what I've been thinking, we could just do both; there's no 
conflict and both solutions are pretty non-invasive.
