Layer group visibility toggle

Question

With the help of this forum I obtained a script  which toggles the visibility of a specific layer without  selecting the layer.
I would like to find out if the same functionality can be achieved for a layer group.
In other words can script toggle the visibility of a layer group with out actually selecting the layer group?
I understand some parts of Photoshop are not scriptable and wan to make sure this isn't one of them before I embark in creating the script.

I have a script that does what you need. Can't remember if I obtained it from here, but I do know that the scripting guys in here are geniuses and can help you out with almost anything. That said, here is the script that you need. All you need to do is replace the three "Insert Layer Name Here" portions with the name of the layer you wish to toggle on/off. Don't thank me, thank whoever wrote it, (most likely someone here)
var targetID = getLayerIDByName('Insert Layer Name here');
if(undefined != targetID){
    if(getLayerVisibilityByID( targetID ) ){
        hideByName('Insert Layer Name here');
    }else{
        showByName('Insert Layer Name here');
function getLayerIDByName(name) {
    try{
    var ref = new ActionReference();
    ref.putProperty( charIDToTypeID("Prpr") , charIDToTypeID( "LyrI" ));
    ref.putName( charIDToTypeID( "Lyr " ), name );
    return executeActionGet(ref).getInteger(charIDToTypeID( "LyrI" ));
    }catch(e){}
function getLayerVisibilityByID( id ) {
    var ref = new ActionReference();
    ref.putProperty( charIDToTypeID("Prpr") , charIDToTypeID( "Vsbl" ));
    ref.putIdentifier( charIDToTypeID( "Lyr " ), id );
    return executeActionGet(ref).getBoolean(charIDToTypeID( "Vsbl" ));
function hideByName(name) {
    var desc = new ActionDescriptor();
        var list = new ActionList();
            var ref = new ActionReference();
            ref.putName( charIDToTypeID('Lyr '), name );
        list.putReference( ref );
    desc.putList( charIDToTypeID('null'), list );
    executeAction( charIDToTypeID('Hd  '), desc, DialogModes.NO );
function showByName(name) {
    var desc = new ActionDescriptor();
        var list = new ActionList();
            var ref = new ActionReference();
            ref.putName( charIDToTypeID('Lyr '), name );
        list.putReference( ref );
    desc.putList( charIDToTypeID('null'), list );
    executeAction( charIDToTypeID('Shw '), desc, DialogModes.NO );
EDIT- whoops, I just realized this is only for layers, not groups. But hopefully it's a starting point
