It is kind of tricky;  implementing the filter in
'PortalFolder.object{Ids,Values,Items}' hardwires a policy into the
class, which is probably not cool (and we would want to use
'content{Ids,Values,Items}' anyway, lest we break the ZMI somehow).

I think that this is a good case for a utility component, implemented
much as Carl's PythonScript, which allows the policy to be pluggable.
