Building and running something like this in Salesforce is a MAJOR PITA, but I do think the platform provides an interesting ecosystem to explore use cases.

Still needs a lot of work to be "stable", but I actually could see it being useful for certain use cases.

If you're interested in checking it out, but don't want to fire up an org yourself, I made a demo video: https://www.youtube.com/watch?v=zLP33ssXUfU

(Sorry for the AI voice over; it's more bearable than my own. And also for the promotion bit at the end; have to justify all the time I spent on this somehow :)
