[REQUEST] Extension of service to other MOOC websites like edX, Udacity, etc.

[rover0000]

Hi,
The Coursera video downloader is quite convenient when it comes to downloading tons of videos from Coursera. It would be a great bonus if you could extend this functionality to other major MOOC sites as well (edX, Udacity, Udemy, etc.). I'm not sure how complicated the process might be, or if it's even possible; it would be a great bonus though, and hence the request. Thanks in advance!
