 I've thought about building a specialized folder, but I'd rather not.  Zope 
 already has a good folder with all the things I need.
 

At this moment, my QuotaFolder only limits the total number of objects,
their total size (sorta) and the maximum size of individual objects.

Future plans are to restrict installable types in general (i.e. restrict
people from installing LocalFS, etc), or to limit the number of these
objects.

If you want to code something like this yourself, QuotaFolder may be a good
startingpoint. I will release the product later this week, but people who
want a preview now should email me and I'll send the current version (which
basically lacks some documentation)

Ivo

Does OrderedFolder do what you want?  See
http://demo.iuveno-net.de/iuveno/Products/OrderedFolder (item 3 in the list
of features).  It may or may not be a standard folder feature in 2.6 as
well.

If you put this in your product:

def all_meta_types(self):
 What types can you add to this objectManager? 
allowedMetaTypes = ('DTML Document', 'DTML Method')
result = []
for metaType in Products.meta_types:
if metaType['name'] in allowedMetaTypes:
result.append(metaType)
return result

You can probably modify it to your needs.
