But there we are, Startup 'seeding; is unavidable, but thereafter ... 
among other things, looking to reduce the reliance on rsync (and 
similar CVS'ish or git'ish techniques) having to 'inventory' stuff at 
a high per-file level that a 'hammer mirror-stream' (or GMIRROR to 
networked RAID) could do 'as you go along' at a lower level - closer 
to the actual blocks as they are being written.

How, and how well, would ZFS handle redundant pools on separate sites?

And can that be a streaming process - even if that means the 
redundancy target is r/o for 'the duration', as a hammer slave would be?
I have not tried it myself, but there is a ZFS send/receive command,
that might do the trick.
