I see. It might be interesting to use with a hard drive (or RAID 0 set) as a write-behind cache, once that is implemented. Or perhaps in front of a high-latency DRBD device. Some interesting possibilities! :)

Why would you want it in front of a DRBD device? If you really want to sacrifice reliability for performance with a DRBD device, simply use protocol B or C, it will likely be more reliable.
