public function deliver(array $output = array()) {} is either not necessary or at least needs to return FALSE. It's an abstract class implementing an interface containing this method so if you leave out the method then any classes extending this will need to implement their own deliver method.
$wrapper->type->{MESSAGE_FIELD_MESSAGE_TEXT}->get(0)->format->value(); type is protected in EntityMetadataWrapper.
