One way to approach this would be to interpose all calls to the TCP interfaces (pretty straightforward with Wasm Components), and tunnel it using Websockets (or whatever) to a server that can make the actual TCP connections on your behalf. So the application running in Wasm doesn't know any different, at least. I guess that's not quite what you wanted, but browsers don't allow making arbitrary direct TCP connections, so in general I don't think there _is_ a way to do what you wanted.
