It's funny--I read about this sort of cryptographic composed graph in a
research paper (back in grad school) and I _wanted_ it then.  I noted
how soon I had Sun engineers touting the feature (and trying to sell us
on it).

I no longer manage large systems or large deployments, so my
sysadminning is personal (and not at the scale of some of the personal
collections on this list--oh my).

There have always been constraints that have limited my (personal)
opportunity to deploy a system supporting ZFS.  Right now it's space and
decibel limits.  So I try to content myself with using git where it's
important on top of a filesystem on top of LSI RAID card.


But yeah, I would have ZFS if I could :)
