Yes - but I wouldn't put too much emphasis on the "easily" part. I think that the physics are now pretty deterministic if you run a simulation using the exact same input/setup (on different clients). However, in reality you'd still have to synchronize the state of the objects every now and then (e.g., if a client didn't receive certain inputs on time).
