Maybe a dumb question, but can I run Krustlet in the browser? (maybe via browser WASI polyfill?). Does this mean you could assemble ad-hoc clusters using volunteer browsers? Not saying one _should_, but could you?
It sounds far-fetched, but I think it may eventually become practical with WASM and WebRTC, to use peer-to-peer networking for distributed computing.
Closest example in that direction, I've heard of malicious WASM payloads that mine cryptocurrencies:

I'm optimistic that people will find socially beneficial application of this idea.
