[Zope] versioning application

I am wondering if anyone is using zope as versioning repository. We have a group of researchers that need some kind of version control system. The need to control versions of data sets, and office documents. I was wondering if anyone had implemented some a version control system in zope, cmf, or plone -- and was using webDAV to access the files. -- David Bear What's the difference between private knowledge and public knowledge?
