hmm, I see how you would use invokeFactory, though I'm not sure if 
the call is to the invokeFactory() from the PortalFolder class, or 
somewhere else. It's a bit fuzzy to me at the moment.

You can set allowed_content_types at the portal_types level by 
setting filter_content_types to 1 (true), and providing a list of 
allowed portal_types. In essence this restricts what types can be 
created within a folder or folder derived product type.

I'm wondering if the attributes that control filtering can be 
applied locally such that a portal folder can have individual and 
unique lists of allowed content types without having to create a 
new portal_type.

Looking at the 'allowedContentTypes' definition in 
CMFCore.PortalFolder, it appears that this only uses information 
from the portal type.

The reason for the question is, I'm trying to avoid creating a 
bunch of portal types just to restrict what type of object can be 
created in a particular folder.
