You can achieve this by adding a normal directory to sys.path:

1. create a base directory
2. create a directory called 'Products' in it
3. put the setuptools magic into an __init__.py into the Products
directory so it contains:
__import__('pkg_resources').declare_namespace(__name__)
4. add any of your plain 'products' into the Products folder
5. add the base directory to sys.path

I think it makes little sense to introduce a special legacy Zope2
concept to ZODB3. Especially since there's an easy workaround like
described above and actually repackaging products into full packages
is a 15 minutes job each.
