This thread seems pretty active again, so I figured I'd post some recent findings in hopes we can all solve this thing.
I found a bacon (v2) message within the height bit-stream that when decoded appears to be "thefm auriskeyfile".
This is a real breakthrough, thanks for sharing this.
Edit: Where did you find the code for bacon? Wrote it yourself?
Yes, I just wrote it myself. It's basically binary mapped to a-z. The version in the code above is Bacon version 2 which does not skip i and v.
