Not truly generically, but for the most part yes.
This will be improving dramatically.

Probably doable.

Yes.

We're pretty good in that department. There are holes: in JavaScript,
VrmlMatrix is missing and directOutput isn't properly supported. Tom

You can get the root nodes from VrmlScene and basically walk the scene
graph until you find what you need.
