Looks like 'view source' reveals the true motivation, commented out ;-)

I came across this recently: http://www.proctoru.com/
The endpoint is a model that will satisfy the employers - whether that's webcam or live proctoring or any combination thereof is irrelevant.
One variant of live proctoring could be an arrangement in which universities give students a number of online options to fulfill a particular requirement - cs, math, physics, etc - and administer their own exams. So the university would simply use it's brand to issue the stamp of quality. In a sense - this is cannibalism for the university. But I think there are public schools that are struggling to serve their students in a financially feasible way. This could be a good way to streamline...
This is absolutely huge.
