Please correct me if I'm misspeaking, but I thought I had read that you intend to open up the design and HDL once you were satisfied that the bulk of the work was complete. I realize that there aren't as many hardware/HDL savvy contributors as there are software, but would even a half dozen new contributors help with ironing out compatibility and performance?
Either way, I am grateful to you for your work on this and look forward to an eventual release. I'm just now delving into my own first embedded projects and am not now anywhere near able to take on a project of this scale, it's inspiring to know that it is possible.
