I'd be more interested in enabling people to build these types of storage systems without touching qemu.

Both sheepdog and ceph ultimately transmit I/O over a socket to a central daemon, right?

That incurs an extra copy.

So could we not standardize a protocol for this that both sheepdog and ceph could implement?

The protocol already exists, nbd. It doesn't support snapshotting etc. but we could extend it.

But IMO what's needed is a plugin API for the block layer.
