[Zope] Needs some ammunition.

My damn Art Director wants to use TeamSite by http://www.interwoven.com/, of course we're not. We are going to use Zope. I was wondering if anyone has had any experience with TeamSite so when I speak with them on the phone I can put them in their place. It seems all it is, is CVS with added work flow control. I don't have that much experience with Zope yet, does it have some sort of work flow control? Any help is as always, greatly appreciated. -chad
