Microsoft® Content Management Server 2002 Connector for SharePoint™ Technologies enables you to integrate Microsoft Office® SharePoint Portal Server 2003 and Windows® SharePoint Services 2.0 technologies with Microsoft Content Management Server (MCMS) 2002 to create an end-to-end solution for document publishing.

I saw a demo a couple of months ago, built on the beta which looked very nice.
