This seems pretty interesting. What would be the use-cases? I can't imagine that it would be a good fit for real-time (a screenshare app like Hangouts or Skype solves that) -- perhaps server logs in a browser tab?
While tools like zoom allow remote desktop control, it still has lag, and the requirement for both parties to install software as opposed to just the sender in the case of this tool.
Awesome, I didn't know that the other person could interact with it -- as in one person's terminal is now a shared browser tab that can have commands entered in? If so, that is really cool and I will check it out further.
Edit: I just viewed the gif again, this time a little longer, and this is really cool!
