Babel-USB: USB drive with every file

The readme explains how to set this up, but it doesn’t really explain what it does. What does this do? I’m guessing it pretends to be a flash drive containing infinite books and then somehow fetches them on the fly from the Internet when the operating system attempts to access them?

I like this. Some binary running on a computer serving these up to a FUSE mount would stop a corporate disk scanner in its tracks (at least whatever thread happens upon the location this is mounted.)

I might have a go writing something like this for my Mac.
