I'm trying to set up a remote game night with this game, and most of the people involved are couples. I'm trying to figure out if we can save on TTS copies (and internet bandwidth) by letting the people in one household share a screen and use it to control two pieces at once--will this work at all with the Betrayer mechanics? Or do we need one TTS copy per player for this to work?

(assume people can be trusted to just not look at the screen for the secret Betrayer parts)
