linux-wasm is an awesome project, but relies on compiling the kernel itself into WASM. This seems to work in principle, but is still a bit unstable. But I do hope that eventually one can get rid of the emulator in the middle as is done in c2w.
Thought this could be useful. Opus 4.5 helped me build most of it, including a simple network stack so that the VM may access the outside world. Still at a very early stage, but I think it looks promising.
