Like DRBD, it looks like it can return completion if the update has landed in memory, but not disk, on the remote node; written to disk on the remote node, or immediately upon being written on the local node with the remote node being updated asynchronously.

Guess I need to read-up on the implementation, things like whether is is async or sync would make a lot of difference; still looks interesting.
