Cahoots Camera Experiment Successful!

I experimented a simplier example related to our team project "Courtroom Cahoots" with switching/swapping multiple cameras.  Here's the script I used:

function Update () {
 if(Input.GetMouseButton(0)){
  Debug.Log("Using Camera One");
  camSwap(1);
 }
 if(Input.GetMouseButton(1)){
  Debug.Log("Using Camera Two");
  camSwap(2);
 }
 if(Input.GetMouseButton(2)){
  Debug.Log("Using Camera Three");
  camSwap(3);
 }
}

function camSwap(currentCam : int){
 var cameras = GameObject.FindGameObjectsWithTag("cam");

 for (var cams : GameObject in cameras){
  cams.GetComponent(Camera).enabled = false;
 }  

 var oneToUse : String = "Camera"+currentCam;
 gameObject.Find(oneToUse).GetComponent(Camera).enabled = true;
}

Only problem with this script, it can switch up to a max of three cameras assigned to separate keys or mouse buttons.  Can't go beyond three at a time.  In our project, we're using more than 20 cameras and having major issues accessing all of them to make our game "work."  Wish there was a simplier way to do.  I know I'm on the right track, but this is where everything's on a complete hault as of right now.
