Using Zoom is totally fine for pair/mob programming, but if you want a collaborative IDE, Cloud9 offers this functionality, and everybody on the task can hop onto Zoom (or really anything) in order to facilitate the audio/video. People behave as though there is no way to do this because of their preference for doing it live (the "proper solution"). But this is absolutely possible and I would say actually better facilitated using these tools than everybody gathered 'round a single machine. Anybody can jump in at any moment and make a comment and a change and have it immediately propagated to everyone else's screen. No need for "Let me sit in the chair" or taking five minutes to nitpick over the minutiae of programming to convey an idea.
