Hello im looking for a solution, so far i have managed to use a textmesh component that is attached to and object, which is a child of the instantiated prefab, therefore each user has this textmesh object. I have edited code based on chat scripts to make arrays of all users. This script works for two connections, both can see eachothers names above thier avatars head but when the third connects serverside remote 1 and 2 swap usernames and on clients remote 1 & 2 have the same username, lookin for advanced advice on how i can make this work. Thanks.

Namespace..

public var UserName: GameObject;
public var Cam: GameObject;
public var player : NetworkPlayer;
public var username : String;
public var awakeName: String;
public var remoteUsers : int;
public var remoteInt : int = 1;
public var userList = new Array();
public var userName: String;

class UserNode{
var userName : String;
var networkPlayer : NetworkPlayer;
} //

body..

function Awake () {
userName = ConnectGui.playerNameInput; // this is a PlayerPrefs.GetString in ConnectGui script.
awakeName = userName;

if(networkView.isMine){
    gameObject.tag = "LocalName";
    gameObject.GetComponentInChildren(TextMesh).text = awakeName;
}

    if(!networkView.isMine){
    gameObject.tag = "RemoteName";
}

    RemoteNameInst (); //renames this object from username to unsername1 ...2 ...3 etc.

    if(Network.isClient || Network.isServer){
    networkView.RPC ("TellOurUser", RPCMode.OthersBuffered, awakeName);
}

networkView.RPC("MeshName", RPCMode.OthersBuffered, awakeName);}

    function Update () {

remoteUsers = userList.length;  
UserName = GameObject.FindWithTag("LocalName");
UserName.transform.localPosition = Vector3(0, 2, 0);
Cam = GameObject.FindWithTag("MainCamera");
var direction : Vector3 = Cam.transform.position - UserName.transform.position;
transform.LookAt(UserName.transform.position - direction);

    }
