Some code in Catalog.py leads me to think this
might be possible.
                    for k, intset in sort_index.items():
                        if hasattr(intset, 'keys'): intset=intset.keys() 
                        append((k,LazyMap(self.__getitem__, intset)))


However, as of the end of 2001, we're told no one
was working on it.

Then...there was a patch to do it.

But it says that Zope 2.2.x handles it.

So...I'm guessing you can now do it, but I don't
see exactly how.  I'll bang on it some more...
