I love this idea but the four remote people are on a slack video call and projected to the big screen in the conference room. I can't imagine the response if I was seen walking around in the background cleaning stuff up.
Say your connection is rough and the quality is cutting so you’re just going to audio only?
In a sense, being in the conference room is asking people to be (ostensibly) 100% on during the whole meeting, which seems like a huge mental drain.
