Glusterfs isn't really object storage (unless they've changed since I last looked at them), and it already more or less works with Dovecot using the existing mailbox formats. Except last I heard it still caused index file corruption. Openstack Swift support is coming. There's a half-working version of it already, would need just a day or two to finish it up. I haven't looked at Ceph closely yet, but it would be nice to support it as well. obox can also be used with a regular POSIX filesystem, although it loses the prefetching capabilities then. So it could be used with e.g. Glusterfs or NFS to provide an efficient local cache. I've also thought about trying out if prefetching could be done by creating new "diskio" processes with a ton of threads doing the actual disk I/O.
