We will need to evaluate the difficulty of maintaining
two publishers.  It is easier to support two servers because WSGI
provides a nice interface for abstracting server differences.

The pubisher is far more tightly integrated.  The first effort
should be to use a single publisher for Zope 2 and Zope 3.
