This module enforces quotas set for the entire Drupal site. It was written for the Aegir Hosting System to enforce quotas set by Aegir administrators on client sites, but could be used with any Drupal hosting system that prevents site users from editing settings.php, where the limits are set.
It works by preventing new entities from being creating on form submission if associated resources are at or past their limits.
