Yes, the todo list is out of date. > Still, even the 15-20% storage gain on an average large pool mentioned > there isn't to be taken THAT lightly ;-) Sure, but it really does require a significant set of changes. My long term plan would be to combine this with implementing time-reverse deltas to store the backups. That's a major rewrite that would also be incompatible with current pools.
