Can anyone point me to an online courselab course? I'd like to see it in action.

I could dump something on the web but it wouldn't be on an LMS. It would be pretty much the same as running one of the samples on here.
If you want to experiment then a good idea is to get a copy of XAMPP on your PC, install an LMS like Moodle and then you can try out as much as you want to with Courselab.
