I just listened to Will on a podcast, and apparently, they're going to package Python apps with a terminal such as xterm.js to solve the Python distribution problem (either as Electron apps or in the web browser), then have customers host their "TUI" apps on proprietary Textual infra- basically a PaaS. He mentioned charging for features like SSO. The library itself would stay free for offline use and you could "pip install" any Python apps that use it.
