I would vote for video for Craig and Pete and audio only for other guests. Cameras use a lot of bandwidth, and with shutdowns occurring all over bandwidth is becoming more precious as more people telecommute, stream videos all day, etc. Also have been teaching remotely for two weeks, I have learned audio is better if people dial in versus using through the computer. At least through Zoom, dial in connections are an option. Furthermore, the most reliable and clear audio hands down is achieved if people dial in on a landline than a cell. It is all about conserving bandwidth right now like we've learned to conseve water.
