Controlling Course Access in Clients' LMS - Possibilities?

Hey everyone! 

I'm starting to offer "licensing" for some of the courses that I've developed in both Storyline and Rise.

Basically, a company can purchase a license to host my content on their company's LMS.

Currently, pricing is based on the number of learners and the duration of the license term.

So the question is, are their solutions that allow me some control over course access in someone else's LMS?

I think some of the large course providers like Opensesame work similar to this. Companies will purchase a certain number of course licenses through their platform, and they'll have the ability to launch the courses within their own LMS.

The licensing that I've already sold have simply been based on the "Honour System". 

While most companies are honest, I've already had a couple of clients drop off the face of the earth at renewal time. So basically they're likely still using my content on their LMS, and I have no recourse and really no way of knowing. It would be great to be able to "turn it off". 

Also, it would be great to see the number of times the course has been completed. This would allow the greatest amount of transparency and control.

I recall discussing this a few years ago when there was no good solution, and I'm hoping that things have progressed and there's a workable solution.

Thanks!
