Spike Instructions

Try spending up to a day to do this and see where blockers appear and find what we don't know and if we can reasonably continue it right now. Document blockers that appear in this ticket so we can discuss them. Expect code generated from this to be disposable.

We spent some time and decided it was achievable, so we started doin it.
