it's good to see that someone other than me is monitoring the check-ins and
this response allows me to give an update about the server code.

Yes, though WSGI is not as much magic as everyone expects. If you want to
connect to another Web server, you will have to write some glue code, but it
demonstrated in the zope/app/wsgi/README.txt file what has to be done. I hope
that through the Twisted integration we will see some opportunity to
generalize and *maybe* we can find a way to allow changing servers by
modifying a couple of lines in a configuration file.

Yes. Instead of passing in a request factory, as it is the case for the
publisher HTTP server, you pass in the application callable. This is very
easy indeed. Note though, that we are not planning to support zope.server
anymore and we will switch to twisted only. I basically did the ZServer WSGI
version as an exercise for the Twisted integration.

Twisted is not integrated yet; I have only created a link to their repository
and made the required license remarks. But the new twisted.web2 code is WSGI
compliant and we will connect to it via WSGI. But the first step will have to
be to throw out the old ZServer loop and replace it by Twisted's. Once this
is done, adding servers, be it HTTP (via WSGI or not), FTP, SMTP, or others
should be a fairly straightforward task. Also note that WSGI makes it much
harder to include the user in the logging (i.e. the current approach will not
work) and it will be trickier to implement clean server shutdowns and
Since Itamar lives in Cambridge these days, we are going to meet this weekend
and work on the full Twisted integration. I hope that foom (James), the
author of twisted.web2, will be able to join us as well.

I think Phillip v. W. wants to look into this.

Thanks, but actually I am just interested in the Twisted integration, since I
really want to see how we can hookup other protocols such as SMTP and POP3 to
Zope 3. Jim really wanted WSGI for the HTTP server and since Twisted supports
it I thought I learn about it some more; thus the documentation cleanups and
