Mike,
I've been researching Content Management Systems (CMS). I can't find a good listing of existing systems out there.
So far, I've heard about the same things about zope that you have (better than php). But, I've heard good things about enhydra (better than zope), but it's java based.
Here are some php based CMSs:
www.midgard-project.org
www.egrail.com
www.back-end.org
I know there was another one out there using php3 (not php4)... I can't seem to find it now! If anyone knows of other "working" systems (there are a lot of CMSs planned) please add it to the list!
Thanks
Jim
