There's on thing that could cause trouble:
Some meta types (e.g. 'Document') have a different text format ('html', 
'structured-text' or 'plain') depending on their text_format attribute. 
How would I implement different editing views for one Node class 
depending on an attribute? Or how would I get different Node classes for 
instances of one meta type?

One thing that confused me was this:

Views are defined
- for Zope in the node as defaultViews / additionalViews
- for the rest in the controller as DefaultViews / AdditionalViews

Maybe you could give me some hints. I quote ZopePTHTMLView because I 
have some questions about it.

class ZopePTHTMLView(ZopeViews.ZopeHTMLView):
     viewName = 'Source.html'
     def generatePage(self):
         props = self.model.zopeObj.properties
         url = 'http://%s:%s@%s:%d/%s/source.html'%(props['username'],
               props['passwd'], props['host'], props['httpport'],
               self.model.zopeObj.whole_name())
         import urllib
         f = urllib.urlopen(url)
         return f.read()

Q1) zopeObj doesn't work. Should be 'self.model.transport'. Right?

Q2) generatePage() is used by additional read only views. For editable 
data I have to use load() / save(). Right?

Q3) urllib.urlopen() is a workaround. I should better use getResource() 
if possible. Right?

Thanks. I'll see what I can do.
