[Zope] Using Client.py for remote admin

I have setup an administrative instance of Zope which will be used to manage and control a bunch of other instances. It's most convenient to be able to invoke methods from the administrative instance, but have all the action happen on the managed instance. For example, the administrative machine may want to create a ZDiscussion... Client.py seems well suited to this, but it seems to demand basic authentication rather than the cookiecrumbler approach I use. I'm a bit stuck as to how to work around the authentication issue. Other than that, everything seems to be working swimmingly.
