[Zope] Object type association in ftp

Hej, I'm actually developing a product for zope and I now have exactly the problem described in http://www.zope.org//Wikis/DevSite/Proposals/ObjectTypeAssociationAndDeathT oIndexHtml - changing the standard association between file extensions and object types for ftp access. As I can see on the page http://www.zope.org/Wikis/DevSite/Projects/Zope2.6/ProposedFeatures (the proposed features for zope 2.6) this should be solved for Zope 2.6. My question now: Is it really solved and is there any example or howto, where I can see how to implement it? Thanks, Andreas
