SoapServer is an attempt to integrate SOAP capability in to Zope.

SoapServer will provide you with an HTTP server that can still do
things that Zope's built in server do - HTTP and XMLRPC

You can easily replace Zope's standard http-server with soap-server

Problems:
* Will break CookieCrumbler(CC).
  CC will check if req.__class__ is HTTPRequest
  and raises CookieCrumblerDisabled if req isn't coming from
  ZPublisher.HTTPRequest.HTTPRequest.
  Solution: 
    after line: from ZPublisher.HTTPRequest import HTTPRequest
    add following lines:
    try:
        from Products.SoapServer.HTTPRequest import HTTPRequest
    except:
        pass
