I don't know if anybody noticed #ZeroFS yet, but it seems there is a completely user space-implementation of #NFS and #blockstorage on top of #S3 #objectstorage: github.com/Barre/zerofs
Including a demo running #ZFS on top of it which essentially allows geo-redundant ZFS volumes: asciinema.org/a/728234 & github.com/Barre/zerofs?tab=re…
