Has anyone ever tried and/or succeeded at integrating a SCORM player with Craft?
Not sure about specific integrations with Craft per se, but one way to achieve this fairly quickly is to integrate with SCORM Cloud's API. It is a SaaS offering that can be leveraged to add SCORM capability to just about any site, LMS, CMS, etc. Integrations with Moodle, WordPress, etc. already exist.
