If someone makes an open-source, easy-to-use, self-hosted API integration with Zoom that lets me set time limits (with Google Calendar integration to determine length) on Zoom calls and (1) somehow posts a warning ~5min before the end and (2) terminates the call at the end, I would pay for it. (If someone reading this is seriously interested in hacking on this, get in touch with me by tagging me (@sqs) in a GitHub issue or something, and I can lay out more detailed specs.) I don't want to pay more than one person for it, so I'm not sure how to coordinate, but I would pay like $2000 USD.
