I've been doing research into code live streaming since I might do it sometime soon. One of the most important things about live streaming is archiving, so people who aren't online and free at that exact moment can still get value from the stream. Twitch has VODs, YouTube and Periscope auto-archives.
According to the sign-up blurb on the right of the window, forced-signing-in-to-watch-videos is the intended behavior, which puts a lot of doubt on the startup sign-up metrics provided. I will never use this service.
I attempted to load the archive of the linked Stephen Wolfram video and hit this: http://i.imgur.com/m1TEJHS.png
