See http://milek.blogspot.com/2007/03/zfs-online-replication.html
Basically we've implemented a mechanizm to replicate zfs file system
implementing new ioctl based on zfs send|recv. The difference is that
we sleep() for specified time (default 5s) and then ask for new
transcation and if there's one we send it out.
More details really soon I hope.
ps. zdb output sent privately
