We developed Object Mount (formerly cunoFS) (https://www.storj.io/object-mount?hn=1) specifically to not rely on any metadata storage other than S3 AND preserve 1:1 mapping of objects to files AND support for POSIX. We have a direct mode that uses LD_PRELOAD to keep everything in userspace so no FUSE overhead.
This approach isn't right for every use case and juice might be a better fit for this sort of 'direct block store', but wanted to include it here for folks that might want something like Juice but without having to maintain a metadata store.
