even though there is some common history and some ascii format
common between VRML and OI, they are not the same, and I don't think
there is any need for them to march lock-step.
VRML is not OI

Once again as I did last year - I call to the moderators of this list to
speak directly to this issue, inform the readership how this issue is to
proceed, state clearly what lines of responsibility exist ( or don't exist),
and generaly manage the public debate about this issue before it descends
into the pit of E-hell again. As it did once before.
To the readership I say, please lets be aware that there is more at stake
here than preserving our individual training exercises, or beginning steps.
Mark and Tony threw away their entire first years work to adopt the current
spec.
VRML has injected a vitalising element into the equation because it is not
the property of an omnipotent indus-diety .
VRML is the enabling technology that allows us to *see* the signs pointing
the way to distributed interactive goals. Don't mistake the sign for the goal.
