PHP MySQL Zend-ACL - Графическое отображение ACL:

Сам по себе ответ почти такой же длинный, как и вопрос, но он работает для меня, давая очень четкое представление о том, на что способна каждая роль. Вот он, если он кому-то поможет:

Теперь о коде:

AdminController:

public function aclAction()
{
    $this->view->content_title = "Access Rules:";

    // Get the ACL - its stored in the session:
    $usersNs = new Zend_Session_Namespace("ZEND_SITE");
    $acl = $usersNs->acl;

    // List all Roles in the ACL:
    $roles = $acl->getRoles();
    // Pass the roles to the view:
    $this->view->roles = $roles;

    // Check if a role has been clicked on:
    $role = this->_getParam('role');
    if(!is_null($role))
    {
        // Pass the role to the view:
        $this->view->role = $role;

        // Get all the resources (controllers) from the ACL, don't add roles:
        $controllers = array();
        foreach ($acl->getResources() as $res)
        {
            if (!in_array($res, $roles))
            {
                $controllers[] = $res;
            }
        }

        // Create a Rules Model:
        $rules = new Model_ACLrules();

        // Store controllers + access:
        $all_controllers = array();

        // Check if the controller has been passed:
        $cont = $this->_getParam('cont');

        // Loop through each controller:
        foreach ($controllers as $controller)
        {
            // Get all actions for the controller:
            // THIS IS THE PART I DON'T LIKE - BUT I SEE NO WAY TO GET
            // THE RULES FROM THE ACL - THERE LOOKS TO BE A METHOD
            // BUT IT IS A PROTECTED METHOD - SO I AM GETTING THE ACTIONS 
            // FROM THE DB, BUT THIS MEANS TWO SQL QUERIES - ONE TO FIND
            // THE RESOURCE FROM THE DB TO GET ITS ID THEN ONE TO FIND
            // ALL THE EXTRAS FOR IT:
            $all_rules = $rules->findAllActions($controller);

            // Store if the role is allowed access somewhere in the controller:
            $allowed = false;

            // Store selected controller actions:
            $cont_actions = array();

            // Loop through all returned row of actions for the resource:
            foreach ($all_rules as $rule)
            {
                // Split the extras field:
                $extras = explode(",", $rule->extras); 

                // Check if the role has access to any of the actions:
                foreach ($extras as $act)
                {
                    // Store matching selected controller:
                    $match = ($cont==$controller)?true:false;

                    // Store the action if we are looking at a resource:
                    if ($match)$temp = array("action"=>$act,"allowed"=>false);

                    // Check if the role is allowed:
                    if ($acl->isAllowed($role,$controller,$act))
                    {
                        // Change the controllers allowed to ture as at least one item is allowed:
                        $allowed = true;

                        // Change the matched controllers action to true:
                        if ($match)$temp = array("action"=>$act,"allowed"=>true);
                    }

                    // Check if the action has already been added if we are looking at a resource:
                    if ($match)
                    {
                        $add = true;
                        // This is done because there could be several rows of extras, for example
                        // login is allowed for guest, then on another row login is denied for member,
                        // this means the login action will be found twice for the resource,
                        // no point in showing login action twice:
                        foreach ($cont_actions as $a)
                        {
                            // Action already in the array, don't add it again:
                            if ($a['action'] == $act) $add = false;
                        }
                        if($add) $cont_actions[] = $temp;
                    }
                }
            }

            // Pass a list of controllers to the view:
            $all_controllers[] = array("controller" => $controller, "allowed" => $allowed);

            // Check if we had a controller:
            if(!is_null($cont))
            {
                // Pass the selected controller to the view:
                $this->view->controller = $cont;

                // Check if this controller in the loop is the controller selected:
                if ($cont == $controller)
                {
                    // Add the controller + actions to the all rules:
                    $this->view->actions = $cont_actions;
                }
            }
        }

        // Pass the full controller list to the view:
        $this->view->controllers = $all_controllers;
    }   
}

Далее вид: acl.phtml:

<h2>Roles:</h2>
<ul>
    <?php 
        foreach ($this->roles as $name)
        {
            echo '<li><a href="'.$this->baseUrl('admin/acl') . '/role/' . $name . '">' . ucfirst($name) . '</a><br/></li>';
        }
    ?>
</ul>

<?php if (isset($this->controllers)): ?>
    <h2><?php echo ucfirst($this->role); ?>'s Controllers:</h2>
    <ul>
        <?php
            $array = $this->controllers;
            sort($array);
            foreach ($array as $controller)
            {
                $font = ($controller['allowed'])?'green':'red';
                echo '<li><a href="'.$this->baseUrl('admin/acl') . '/role/' . $this->role . '/cont/'.$controller['controller'].'" style="color:'.$font.';">'.ucfirst($controller['controller']).'</a></li>';

Я надеюсь, что это кому-то поможет, я пока оставлю его открытым, если кто-то может предложить лучшее решение - или, может быть, улучшить ответ?
