   Okay, then this leads me to the strong suspicion that what I'm
(mis)using ViewPageTemplateFiles for is the wrong way to attack
the problem.

   What I'm doing is something along the lines of

	class MyView(BrowserView):
	    def __call__(self):
	        pagename = somehow_compute_new_page_name(self.request,  
	        pt = ViewPageTemplateFile(pagename)
	        return pt.__get__(self, self.__class__)()

   but quite obviously, that's not how it's meant to be used, is it...
Perhaps I need a radically different approach?
