I've played Jackbox games monthly with my family via Zoom. I have a gigabit fiber connection, and they have slower cable connections. The Jackbox timer can be configured to a longer amount, but we've never had an issue with this. Most timer issues have been due to someone being distracted by something else, not the game itself.

Generally, if a group can use any form of videoconferencing, they can use Jackbox. It's no different from one person sharing a presentation. I've only encountered one game that required realtime interaction, and we know to avoid it.

It's pretty easy to get around corporate machine lockdown by using a personal machine to host. Participants are just using the web browser.
