For our non-commercial, community course sharing hub we may have a need to track course usage on various Moodle installs. The workflow is like this: Courses get shared from trusted Moodles via the hub plugin. Members then download those courses and restore them to their own systems.
What I'd like to do is add some Piwik tracking code to all shared courses, perhaps as a label. I am hoping that we can track usage when these courses are restored to other Moodles. Possible?
Thanks for any insight anyone might have.
