Which video hosting would you choose to bootstrap a MOOC website: Vimeo Pro/Wistia or a CDN like Fastly?
From what I've heard, Vimeo Pro might be the better option as far as pricing goes, and I know the player allows for viewing speed adjustment.
Vimeo pro is a great starting point, you can even promote your work using the ‘series/film’ category so maybe you can sell your mooc courses as well in Vimeo or build a community. Everything is valid when you’re bootstrapping a product.
If you listen to Syntax.fm with Wes Bos there's an episode (I don't remember which) where they go over what they use for video hosting and why they chose it. Probably be a good listen and it's a great podcast anyways.
