[Zope] hide nested classes in a python products -- how?

[Tino Wildenhain]

Hi Tobias,

One solution that comes in mind is to remove the
permission "Add your object type" from everyone
and provide a proxy role in your folderish
product.

Another way would ony be to hack ofs.folder
to make the types of objects configureable.
This would also be nice in regard to mime-types
and ftp upload -> object type mapping

Regards
Tino
