[Zope] Version Control in CMF/Plone?

[Iwan van der Kleyn]

A feature I mis in Zope/CMF/Plone is version control of documents. With 
this I mean for example that authors can (minimally) view and revert to 
previous versions of documents. This as opposed to the back-end Revision 
Manager product  which allows versioning of Zope objects in CVS.

I've found a reference to a project to integrate version control in 
Zope. 
http://dev.zope.org/Wikis/DevSite/Projects/ZopeVersionControl/FrontPage.
Is it known what the status is of this endavour?
