How to find network object instance?

Unity Engine
1

In my application, I need to find the networking player “body” for realisation of some actions.
How can I find my gamers body (Transform or GameObject) by the ViewID or Network Player ?

I use the following to get the transform:

var playerNetView : NetworkView = networkView.Find(playerNetViewID);
var thePlayer = playerNetView.transform;

Thanks.
