I've lurked until now, and I'm attention-averse, but here is my toy. I'm certain that I'll regret this, and I'm not sure how much time I'll have to monitor it or follow up, but on the off chance that someone here is stuck at home and wants to play, here it is.

The service is hosted on a CPU-optimized DO droplet in San Francisco. I've set the maximum number of calls to 10, but I have no idea what the real limit will be. I'll try to keep an eye on it. I'll leave it up until someone finds a critical bug or I find that no one is using it.
I post this in response to having read apenwarr's grumpy opinions about remote work at Tailscale, linked here a few days ago (https://apenwarr.ca/log/20200309). One option that wasn't listed is self-hosting Jitsi (https://meet.jit.si/), something I feel is a much better self-hosting option than what I'm showing you here now.
