If I had to list them in order of importance for us, it's: 1. reclaim unused objects automatically 2. add hierarchical zones support 3. use differential copy for fast object recovery Would also love the ability to use vdi read/write to get changed data since last snapshot or something similar to zfs send/recv. Know it's been mentioned before. This might be part of what you are calling 3.
