At a typical reading speed of 110WPM, I don't have the patience for audio books, so they're not on my radar.
Also, given the word count, this would be almost 100 hours of reading. And I have no idea how to handle the diagrams and equations which in many cases are integral to the book.
Now it is possible to do this without a publisher just like the book was done without one.
I don't have the voice, nor the editing skills for this, but I'd support the project.
