Heck, whack it all behind loadbalancers, write a tool to manage it, and you
can do upgrades pretty much automatically, and without any visible outage.

For me, upgrading the production system requires
zopecontrol.py --upgradeserver=prod

It whirrs off to CVS, checks out code, rebuilds it, all that stuff. Makes 
life sooo much more pleasant.
