Such as good start, that I'd like to suggest the 'un-blog-like' course
of correcting the original, at least 'for a while yet' rather than
blogging-on the errata at the tail.
I don't think your ZFS assessment is 100% accurate, so a bit of clean-up
there could reduce flame-bait.
That may earn further alteration if/as/when Sun integrate 'lustre'
features. At present, HAMMMERfs and ZFS have only partial overlap in
their Venn diagrams.
But I encourage you to keep updating and tracking the changes.
Maybe it should open with a date-stamped 'current state of ...'?
