The license is LGPL.  Meaning you can use it in a commerical application
as a library just fine.  As to who can profit, you can, but we always
like custom development projects to spread the wealth :)

My first pass through the code was that their where problems with the
VRML97 parsing.  This is definately one area where using the Xj3D
project could help you.  I tried running the system across some VRML
files and didn't get real far.  I've been rather busy recently so I
haven't had a chance to reall dig into it.  If you wanted to take first
stabs at integrating with Xj3D that would help.  As a standalone project
it doesn't work too well with our goals.  But as a binary format for
Xj3D it would be great.
