Automatically download Node.js binaries if necessary when user builds app

Rather than requiring the user to download Node.js manually in order to build an app, thereby preventing Windows users without administrator access from building binaries, could Electron Fiddle automatically (with user consent) download the latest LTS release binary (`.zip`) of Node.js, unpack it, and append its directory to PATH when the user tries to package an app? Electron Fiddle would be great for education, but requiring users to manually install Node is a major limiting factor.
