Module support?

actually i can give you an example

i'm  working on a B2B solution which is developed in CI;
This shop contains multiple subshops which are consistently quite different to each other (therefore we needed separate modules for each subshop)- and this is the reason why i'm so much in love with HMVC - We have developed our own cart solution as a module and every shop calls the cart controller in the same way to geht the cartview;
(below an excerpt for one of our views and those controllers which are involved)

In this instance you've 2 possibilities:

1. to call the module in the view like 

PHP Code:

<div role="tabpanel" class="tab-pane active" id="add-to-cart">
    <?php
    $objItem->setTranslation("basket_save_button",$this->lp->get("shopcart.to_basket"));
    echo modules::run("Cart/displayCartForShopItem",$objItem);
    ?>
</div> 


2. or to call the module in the specific modules controller and pass the result to the view 

PHP Code:

class Ekf extends Modules_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->model("ekf/Ekf_Model");
        $this->load->model("ekf/EkfCategory_Model");
    }
    
    public function item()
    {
        $this->load->model("ekf/EkfShopItem_Model");
        $this->load->model("userarea/nossns/NosSns_Model");
        $objItem = $this->EkfShopItem_Model->getItem();
        $arrNosSnsCategories = $this->NosSns_Model->getCategories($this->mer->isHeadDebitor());
        
        $strViewCart = modules::run("Cart/displayCartForEkfShopItem",$objItem);
        
        $arrData = array(
            "objCat" => $objCat,
            "arrNosSnsCategories" => $arrNosSnsCategories,
            "strViewCart" => $strViewCart
            "objItem" => $objItem
        );
        
        $this->load->view("ekf/item",$arrData);
    }
} 


and the view looks like

Code:

<div role="tabpanel" class="tab-pane active" id="add-to-cart">
    <?=$strViewCart; ?>
</div>

and the Cart Module looks like

PHP Code:

class Cart extends Modules_Controller
{

 public function __construct()
 {
 parent::__construct();
 $this->load->model("Cart_Model");
 }

 public function displayCartForEkfShopItem(EkfShopItem_Object $obj)
 {
 $objCartWrapper = $this->Cart_Model->loadWrapper($this->mer->getCurrentActiveMerchant()->No_);

 $arrData = array();
 $arrData["objShop"] = $obj;
 $arrData["objCart"] = $objCartWrapper->loadCart("ekf", $obj->saison);

 $this->load->view("order-item",$arrData);
 }
}
