That's very interesting.  It would nicely avoid the solving the really
hard problem of maintaining real-time coherence between two
nondeterministic physics engines over a slow link (which is really a
problem of chaos prevention!).

The first step is to ask: what form does the world state take?  If it can
be represented, for example, as a dict of object names and properties,
then you can simply use the shared-dict from groupthink.  Of course,
getting changes in and out of the model is not so easy.
