No. OpenGL and OpenInventor are not the only rendering engines/toolkits in
the world. Also, there are networking pieces in VRML that are not in
Inventor-- a few now, more to come as we begin to understand the network issues.

You understand correctly. HotJava sounds extremely interesting.
As the Daarmstadt conference approaches, we (the folks who are riding herd
on the spec process) will be sending mail to the list soliciting proposals
for behavior architecture/API/languages. I hope to see HotJava among the
proposals.

Yes, Yes, Yes.
