For some reason (I think it's a known bug) ZEO clients will not 
currently work when started as root, which is necessary in order to bind 
to port 80. (This has bit me recently too.)

As you've seen, the workaround is to start it on a high port as a 
regular user and proxy/masquerade/rewrite/whatever to port 80. It's a 
good idea to front Zope with a proxy anyway, but if it's for internal 
use or you're not concerned for some reason, you can have your OS do 
port masquerading/forwarding. I just put an iptables rule on plone-users 
list that does just that.
