I were waiting for this problem to be opened on our list ;-)
I agese with the fact you exposed, but the real problem is to find a
way to really protect the 3D model, as dongle are for the software
(only few people can bypass them) or it is better just use lsgal way
to protect them.
IMHO the proposed scheme don't help to use lsgal way to protect
3D model (the problem is always the one of ''derived work'').
An ineffective way to insert some protectiom scheme in VRML or browsers
(one that a lot of people can bypass) is just a problem for the people
that are innocent (as disk based protection scheme are for software).
For this esason it must be avoided.
Just my 2 cents..... Marco
