Rigidbodys and Unity Multiplayer

Hi there,

I was wondering how do you handle dynamic objects in multiplayer?
Say for example you made a simple pong game where the ball was dynamic (rigidbody), would both sides be able to interact with that object? So far with multiplayer I have just passed simple position data back and forth so I'm pretty new to it all so this concept was hurting my brain...

Thanks,
Pete
