During a week in 2013 I setup http://sabre.io/ http://sabre.io/ to work with storage backed by S3, I think it was about 40 lines of PHP to add user authentication and the S3 storage plugin. It's so seductive since every file manager on every main GUI OS has some support for WebDAV, and you'd think "what could go wrong?" with just file I/O over HTTP... Some months later I even tried setting something up for my old high school teacher for his CS students to copy files over and receive results back, alas the district network policies got in the way and I'm not sure if it was ever resolved.
