Update array of game objects to all clients

Hi, I have a global array of game objects that the player when joining a game adds its self to at is globalID location in the array, what I want to know is it possible when joining to update the array ?

I know I cannot use something like -

 networkGlobalVarsViewID.RPC ("writePlayerGameObject", RPCMode.AllBuffered, playerNetworkGlobalID, PlayerRoot.gameObject);

Because game objects are not permitted in the RPC call.
