Just as you can create an HTML file out of your hotlist, this should be
possible... if you want some way of specifying that files in a
3D-file-system-representation appear as sheep when the VRML author
expressed them as goats, that's a little beyond the scope here. :)

Windows software should be released within a month, if the press releases
are to be believed. QvLib should compile on a Linux box, but it's
primarily a programmer's tool at this point.

*shrug*.... 3DS?

No. None right now. Work-in-progress.

Consider HTML sitting on a web site. In most cases, can you change it?
No. However, there are places on the web where the content is created by
participants - I created such a system for the discussion areas on
HotWired (http://www.hotwired.com/Piazza/Threads/), but others have done
it as well. Collaborative applications will be very big very soon, and
even though VRML is a static scene description language programs can
generate VRML dynamically just as HTML is generated dynamically.

Not yet - but Watch This Space (tm).

Not yet. It's a Very Big Problem, so we've chosen not to solve the
world's problems and find a solution to world peace at the same time, and
be pragmatic for now. But once the browsers are out there you will see
people clamoring for this - as VRML is based on Open Inventor there is
something of a path for this to take as well.

Definitely not - they may be ones that long-time followers of the list
may not be asking but do bear repeating frequently (whoa, a FAQ seems
like a good idea now...)
