The solution is somewhere in the qemu or kvm world but qemu deals with real hardware. I'm looking for something simpler than a real machine. Ideally, qemu could run a virtual cpu just made for asm.js or wasm. The virtual hardware is accessed thru the Module functions. We could have a peek() and a poke() like in the old days to read the ports :-) I remember your first posts about emscripten and the first script in Python. The gap to fill is similar to "write a backend for LLVM" as you did (not enough, of course). There is also the x86 emulator from copy.sh (http://copy.sh/v86/ http://copy.sh/v86/). The general direction is "support blobs in the browser". About implementing new Web API, I think the process is not so slow but it relies on non-technical things (like strategy for the companies) so low level would speed up that.
