If WSGI lives up to its promise, then the WSGI-compliant Z2-Z3 hybrid
would be publishable as a "WSGI application" from any WSGI server,
including perhaps mod_python-based servers.

twisted) are not well understood in the context of Zope, until some
brave soul actually rolls out a high-volume production site and reports
success or failure.
