Len,

Consider this carefully. You know I don't give in easily to
competing 3D technologies. You remember IBM and Google. I
wasn't shy about telling my opinions, like on the front pack
of attack dogs defending territory. And even in this case I
was ready to charge; it sure is not easy to convince me of
something like this. I resisted change too. Until I realized
that I was not right. This is different. And the approach is
different. No sneaky attack or big marketing campaign to try
and kill X3D. Rather, an honest and friendly visit to come
ask for our opinions. No one has done this before. A big
gamble you might say, but I also believe the market strategy
is sound. The implementation may be a little hard and take
some time, but the basic ideas are too good not to act. We'd
take a greater risk not embracing these developments than
ignoring them. Besides, X3D will continue to be around. I
don't feel I am loosing that. And you know as much as I do
that, like you, I have a lot invested in X3D. CSSDOM may
just be the spark that wakes up 3D on the Internet(and thus
give X3D a boost). We all know this is bound to happen. The
question is 'when'? When the killer app arrives, that's
when. And in this case the killer app may just well be 'no
app'. Brilliant. 

As an artist, and because of the great talent you have, I
believe taking the opportunity to be one of the first
content developers getting initial exposure could really
mean this is your time to shine. What is a singer that
doesn't sing, a musician that doesn't play, and a world
builder that doesn't build?  What you have you will keep,
here is a chance to have more. But this is entirely your
decision to make, as this is only my opinion.

Lauren
