This +1. a permanent test room is innately useful. And a bot which can be told to listen for 5 sec and repeat what it hears (or sees) so you can "know" end to end "it worked" Based on the WG I have participated in, there is some UX work around enabling and disabling microphones, the GUI marks to do this, and the control logic of taking and giving microphone. Also based on the WG I have participated in, some chairs need to learn to mute microphone. The relative volume of key-hitting, throat clearing and drink-slurping is out of all proportion to your local understanding, when a microphone is involved.
