Im on mobile and didnt realize you were project head when I first replied. Id have been more helpful. My bad.<p>Im glad your doing it gradually with intermediates. That will let it benefit spinoff projects or even products hopefully. Plus keep you from getting overloaded.<p>I also like that RISC-V is in your long-term vision. Keeping that in mind early will help avoid architectural mistakes early on. Id say use the ISA closest to it in meantime so little change is necessary.<p>Far as overall scheme, I&#x27;ll email you some reference work if your interested in prior work on safe runtimes, split apps, high-security dev techniques, and so on. Might be able to integrate that into idiomatic Rust. That&#x27;s your call though.
