I would love to see if we can have something similar that doesn't require JS at all, so we can execute x86 programs server-side just using Wasm translation (hi Wasmer).
Here's another interesting project I found recently that I think fits as well on the asm2wasm translation mechanism: https://github.com/copy/v86/
It seems to us that in server-side scenarios it is most usually possible to execute apps natively anyway.
Running user input on a server would definitely be a security risk, but might be nice when everyone is trusted anyway.
Though, if it's server side what would be the benefit of using WASM instead of just running it in the actual languages? I'm always on board for doing weird things just to see if they can be done, so if that's what you mean, I get it. I don't know much about WASM though, so I honestly don't know if there would be any practical benefits of running it server side.
What is lower than container/vms? I was curious about those online sandboxes that are great, can fire code in there/runs it. I imagine they clean out the user input but if you were to assume the container/thing would fail... can it still be considered secure/separate like a glove.
Assuming there's some usefulness on running software through Wasm for its universality and sandboxing properties. The answer for this would be two fold:
1. Compiling programs to Wasm natively is a challenge itself (Emscripten has lowered the barrier by a big margin, but I will argue that is still harder using Emscripten than Clang)
2. You may have access to the binary, but it's still hard to have the tooling needed to compile it down to native/wasm code (meaning: having the right environment, compiler, libraries, ...)
By using a asm2wasm translator layer we will solve both the compiler toolchain and the library/environment tooling needed for running programs universally and safely.
