Hi, I've posted a work-in-progress doc on Zope.org that compares ACS and Zope with regards to things that I care about. I started this a couple weeks back and think that others may be interested in the opinions. If you see any factual errors (particularly if you've actually used a running ACS and I've gotten something way wrong) or have other feedback, send me a message... Check out the document here: http://www.zope.org/Members/tazzzzz/ACSandZope Kevin http://www.byproducts.com - Humor and Novelties
