At Red Hat Summit 2015, Matthew Micene from DLT Solutions presented current status of OpenSCAP ecosystem and mainly how to apply all the pieces to your infrastracture. The video just got online.

I think he made a excellent job describing where we are. It includes introduction to SCAP, OpenSCAP, SCAP-Security-Guide, SCAP-Workbench, RH Satellite 5, RH Satellite 6. But mainly, it connects the dots between the projects.
I wouldn't be spamming mailing-list, if were thinking it is not worth wathing. :)
Thanks!
