It would be focused primarily on embedded processors (all 32-bit & 64-bit processors), likely not 8-bit and 16-bit microcontrollers (although there do exist some 32-bit processors that are categorized as microcontrollers nowadays). The bigger question would be GPUs & DSPs. I'd aim for something like QNX, a ยต-kernel with built in distribution of tasks over the network. >>> b) we should find some financing for such a project and > > That is always the trick: how to have a funding and business model that enables a long-term going-concern. Depending on volunteers and donationware quickly exhausts its limited funding. One of the reasons I've not enabled GitHub Sponsors is because I just don't think people would donate.
