Not yet ;)
I still don't quite understand why you want to handle the animation on
the server side instead of doing it on the client and distribute its
_result_ over the cluster. The main problem I see with your approach is
that you can not just stop receiving data from the client after the
initial scene is transmitted. For example you still want updated camera
and light beacons.
This means you'd have to merge some changes from the client back into
your "pristine" state, which seems rather difficult. Since you said you
want to keep it simple, I guess my question is: why do you believe that
your approach is the most simple one, that gives you what you want ?
Thanks,
Carsten
