Is the goal to provide POSIX file access as NFS and AFS do? The mention of object storage as a future direction feels like the early "the sky's the limit" euphoria of a new project that has yet to adopt specific end goals.
The initial goals that are in this release:
1. An abstraction for replicated storage between machines in a cluster.
2. A block device "application" on top that an ext4 filesystem could be run on. This is like an EBS.
In the future someone might build other applications like "object storage" or filesystems and we would love to get the feedback on the API to do that. But, that isn't in the initial goals and we will be focusing on the storage and block layers for the time being.
