As far as backups are concerned, rsync --link-dest may be an option, however even at best it would only give file-granularity COW as opposed to block-granularity. I'm not sure if this would work for me in terms of disk space consumption. I *think* send/receive with clone sources might be the key to a solution. I'm still hoping that someone with a far better understanding of btrfs than me gives it a try first...
