You could add 'replyCount' to the metadata schema of your catalog,
and then it would be computed only at indexing time -- you would
want your DiscussionItem skins to cause the source object to be
recatalogued whenever a reply was added, though.

BTW, I really like the way ZopeZen looks and works atop the CMF!
