You've got the order wrong. At dispatchLoopShutdown(), the action has
already been performed, and the template already rendered -- the way you
have it now, you're assigning variables to the view object, but then not
rendering anything afterwards (index/index.phtml was rendered *before*
this plugin action was ever invoked).
Make the plugin operate at either dispatchLoopStartup() or preDispatch()
(the first will be executed exactly once, the second during each
iteration of the dispatch loop).

You're actually doing it right. The ViewRenderer is registered at the
beginning of the dispatch loop (or earlier, if you do it in your
bootstrap), and then injects the view object into the action controllers
as they're dispatched. So, the way to reliably get the view object is as
follows:
$view =
Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer')->view;
