Hi Martin, Stefan!

There's a lot of work going on just to solve these issues (TTW / 
filesystem, customization, creating settings, exporting resources to the 
filesystem, ..), but on an application level and not in the way you 
think. What is made customizable is not an entire template, but only the 
resources used by the "template". Also the page composition is done 
entirely TTW. So the need for a template to create an manage entire 
sites disappears.

see for instance:
"Unified model for managing application resources"
http://www.z3lab.org/sections/blogs/jean-marc-orliaguet/2005_11_10_unified-model-for

The separation of concerns (the site manager manages filesystem and TTW 
resources, page designer manages pages, content  author manages content 
, ...):
http://www.z3lab.org/sections/front-page/design-features/editing-screens/

Using ZPT pages to create portlets through-the-web
http://www.z3lab.org/sections/front-page/design-features/custom-portlet/

my impression is that if you want TTW editing you'll have to do it on an 
application level using what's available in the framework (utilities, 
ZPT, ...) Zope3 allows you to do this already and in a much cleaner way 
than with zope2..
