The method _setViewLayout() rides to the rescue!  ;-)  In your app,  
override it like this:

     protected function _setViewLayout($view)
     {
         // change the view object over to layouts
         $view = parent::_setViewLayout($view);

         // now add our own stuff
         $view->addTemplatePath($this->layout_path);

         // done!
         return $view;
     }

Note that the _setViewLayout() method is the only "hook" that takes a  
parameter; i.e., the $view object that was used to run the view  
script).  That $view object is used twice: first to run the view  
script, then it is pointed to the layout paths and re-used.  That way  
all the variables and helpers used by $view stay in place for the  
layout use use.
