I am happy to report that I do have some code nearly ready to share. Though it's still of the prototype/experiment variety (not even remotely production ready). I'll send it out in the next few weeks. Without help, it will still be many months until I have a full stack prototype.
In today's world, I might suggest packaging the experiment up in a Docker if reasonably practical so that people can fiddle with it at the black box abstraction level or test it against the spec without 'it runs on my machine' creeping into the equation. Just a thought.
