[Zope] Developing customer customizable products

[Peter Sabaini]

I'd provide a default DTMLMethod | PageTemplate file and check for a 
ZODB based DTMLMethod | PageTemplate object

Sth like

def render(self, <request, args etc.>):
     template = getattr(self, 'customized_pt', None)
     if template is None:
         template = self.default_pt
     return template(<your arguments>)
