I ended up in the cluster block device design business rather accidently, after being plucked by Sistina Software from a life of leisure and random geekly pursuits in Berlin. It seems everybody else at Sistina was too busy to design the cluster snapshot and nobody really knew how to anyway, including me. But lo! It turned out to be not all that hard, and as a bonus, the same design mostly worked for the cluster mirror device as well. With two cluster block device designs to my credit, I must surely be an expert in the field. Or perhaps I am the only person in the field.
 Acquired by Red Hat shortly after.
