OS/2 Warp did something similar to what you describe, but with FTP sites: You could navigate them using the file manager, just like any other folder, create links, bookmarks, etc. I vaguely remember saving web bookmarks as files, and using the built-in browser to navigate them to them. The shell (WPS) had the philosophy: "everything is an object". It was very cool for its time.
