I’d need help to run such a thing. And not a small amount. Certainly more than answered the poll, though I admit I did a poor job of trying to get it “out there.”
Perhaps a small informal thing to start, with some sort of focus. Where to start? Personally, my vote would be embedded systems (pi0 and similar, not PICs), starting with a 16 MBish system image and tooling for local customization of it.
