Description
So Go now Supports targeting WASM, but with certain limitations (like not having 'normal' syscalls). It's very low priority and probably a bit of work, but would be a nice 'benchmark' of portability.
First step would be to make the thing compile at all, currently stack of errors I get is down to:

Built with GOOS=js GOARCH=wasm go build -tags="nofuse purego" -ldflags="-X "github.com/ipfs/go-ipfs".CurrentCommit=47e9466ac" -o "cmd/ipfs/ipfs" "github.com/ipfs/go-ipfs/cmd/ipfs"
- sha256-simd - fixed in https://github.com/minio/sha256-simd/pull/33, so an update will fix those
- go-reuseport - we should find a way to just disable it, probably by either just plugin-ifying transports or sprinkling build tags injecting dummy things in place of the implementation. Probably a good excuse to fix some technical debt.
- pb (progress bar) - no idea, probably just PR a fix/workaround
Next step would be to write some transport to talk to outside nodes. /ws//wss should be easy to wrap.
