Is anyone aware of particular reasons why the group is pushing on a
syncronous solution? I'm sure they have good reasons, but I would've
assumed an asyncronous solution would be far more applicable for
simple redundancy as opposed to syncronicity for high-performance
clusters, not too mention being far simpler implementations.
