  Perhaps I should have made myself clearer about time frames.  I believe that
individual modules which can maintain multiple conflicting ontologies are
ultimately necessary.  However, I think I'll retired in my rocking chair before
we have them working.  In views on the near term, in fact, I think I'm actually
more conservative than you: I view the kind of layering you describe as
something to work up to rather than something we're clearly ready for.
