I was just wishing for this. Sign me up! I hope this becomes a reality. I'd love to stream while I work. I just need to figure out a way to keep things like our api and secret keys private.
I agree, there has to be a feature so that when a particular sequence of characters gets entered, the screen blurs it out. But even then, it would take many other people using it, and the functionality working, for me to trust it.
Or a private button to push in order to be off air for a while.
