Since VOS was originally conceived as a peer-to-peer system, we had this idea that we could do client-based physics, but that idea quickly breaks down when you have more than one client applying force to a single object. So it will probably end up being something like server-based simulation + client side prediction. Prediction may be as simple as sending linear/rotational velocity and extrapolating from that, perhaps with collision detection so people don't appear to run through things...
One thing I've come to realize is over the Internet lag is often so bad that close synchronization is impossible and the best you can do is make it look good on each client and just hope it's close enough.
