hive VS lumen

That would indeed be super useful to extend self hosted automation tools like Huginn. From what I understand, wasm/wasi modules don't have full networking or filesystem access support yet. So you probably have to rely on specific runtimes to provide hooks for doing that, and regular code won't work out of the box.

There are details on this also: https://github.com/GetFirefly/firefly#runtime

Generally it should be assumed that actors and their concurrency model is fully supported as that is a part of the core semantics for BEAM languages.

I think this project used to be called Lumen until pretty recently - https://github.com/GetFirefly/firefly

Probably not a practical solution for what you are building now, but it's worth pointing out Lumen, an Erlang VM implementation that compiles to WebAssembly, and could one day enable Elixir on the frontend.

Another vector could be some tooling that makes it easy to run Go programs compiled to Wasm run inside of Wasmtime environment hosted in Rust. If we run the go tooling in the same system, one could point this tool at a Go repo and be running that Go in a matter of milliseconds. A fun feature would be running channels across separate Wasm envs. Or maybe use Lumen.

Wish the Elixir WASM project -- Lumen -- were active. It seems like nothing much is happening on it.
