Russell, are you available at some point during EmacsConf? Testing breakout rooms in a group workshop / unconference thing might be fun with more participants. Based on last year's Q&A experience, you might get 30 people or so (or maybe more, if you run it over lunch break or next to a more niche talk). I can probably figure out how to add it to the schedule whenever you want.

It could work like this:

- first 5-15 minutes, people propose topics to talk about while you write them down in a screenshared text editor (Emacs, of course). Might have an informal show of virtual hands (not webcam, that makes the performance bad if there are lots of people; just use the raise hands thing) to make sure people aren't going to be waiting by themselves

- you create the breakout rooms and people join the ones they want

- they discuss; people can come back to the main room and join other things

- you can check in on them if you want

- maybe a report back if people want?

Could be a peer-to-peer help thing, could be an Org thing, could be last-minute demos, could be whatever the participants want... 

If you or anyone wants to experiment with this, let me know what time you want to schedule it!
