The Unofficial System Center Catalog
This table lists all integration packs and objects that you can leverage for your workflows and that I know about. As mentioned on the Opalis blog, also remember that it’s very easy to create new activities with Opalis, using the Foundation Objects and/or – as needed – with the Quick Integration Kit. Some sample workflows are also available from Microsoft at this link.
