1) Is there enough D demand for someone to make a living (bread and water :} ) at it?
You can scan this page for hiring companies: https://dlang.org/orgs-using-d.html
2) I've programmed industrial automation controllers using graphical and text-based languages and wrote a few small command line tools in D for myself. How long would it take to become "employable"?
Look up some programming interview questions and see if you can answer them. I would also suggesting having some programs you've written in a portfolio.
3) Is there much value in taking programming classes that don't deal with D?
Yes, a programmer without CS knowledge is the difference between a mechanic and an engineer.
4) What is the best way to find D programming jobs online?
Post here.
