WASI Preview 1 and WASI Preview 2 can do file and network I/O IIUC.

Re: tty support in container2wasm and fixed 80x25 due to lack of SIGWINCH support in WASI Preview 1: https://github.com/ktock/container2wasm/issues/146

The File System Access API requires granting each app access to each folder.

jupyterlab-filesystem-access only works with Chromium based browsers, because FF doesn't support the File System Access API: https://github.com/jupyterlab-contrib/jupyterlab-filesystem-...

The File System Access API is useful for opening a local .ipynb and .csv with JupyterLite, which builds CPython for WASM as Pyodide.

There is a "Direct Sockets API in Chrome 131" but not in FF; so WebRTC and WebSocket relaying is unnecessary for WASM apps like WebVM: https://news.ycombinator.com/item?id=42029188
