With the icoya CMS, we implemented a similar "Resource"-/"Relay" object approach to 
overcome the difficulties described above. 
Resource objects are the containers (Zope objects) for content objects (located in the 
ZODB, Filesystem or databases). Beside the function as 
a storage container "Resources" implement versioning, languages, link bases and other 
features. To get Resources published, we introduced "Relay" objects. 
The "Relay"-object publish the content of a "Resource" in a defined manner i.e. style, 
variant, version, language, etc.. Furthermore the Relay can be used for  
dynamic folders, personalization and workflow. We have good experience with this 
approach, but at the beginning of our work we had to solve the performance penality 
that arose with the multiple indirection of the content.
