We've been teaching a web development course to a remote team, and I found this really useful! Since we're not native English speakers, I've made English subtitles for the first video, and put them on GitHub, in case anyone else finds this useful: https://github.com/deborasetton/subtitles
I'm hoping to translate it to Portuguese, but would gladly accept pull requests for other languages too!
Also, the other videos are on my to-do list, of course.
I think it would be possible to read the content if it was just inserted into a <div> in the DOM or something. But the priv.ly link that is pointing to the content could be replaced by an iframe, and then it wouldn't be accessible to outsiders code, because of same-origin policy, I think. Not sure how it's actually done, though, I didn't dig any deeper.
