  $nid = $node->nid;
  $view = views_get_view($settings['view']);
  $view
    ->set_display($settings['view_display']);
  if ($view
    ->access($settings['view_display'])) {

    // If this node existed in the system prior to this page request, there is a chance
    // that it needs to be reloaded and thus node_load() needs to be reset.
    node_load($param = array(), $revision = NULL, $reset = TRUE);

    // Get the atom-formatted-data for this node.
    $result = $view
      ->preview($settings['view_display'], array(
      $nid,
    ));

    // Only PuSH the feed if there is actual data.  The view may have filtered
    // our nids down to 0, in which case we don't want to send anything. Because
    // normal View requests (Pull-based) are unaffected, Atom subscriptions still
    // work as normal.
    if (!empty($view->result)) {
      $topic_url = url($view->display[$view->current_display]->display_options['path'], array(
        'absolute' => TRUE,
      ));

      // This uses the Drupal Queue module to actually send notifications later.
      push_hub_notify($topic_url, $result);
