It's coming along quite nicely AFAICT.

I'm afraid I'm not enough of a filesystem expert to keep the
information in my head for very long (I said no-brainer, and I meant
it ;->).  I understood more a few weeks ago than I do today.  There is
plenty of good information out there if you -- um -- use Google :) and
other people can explain it much better than I
(e.g. http://www.opensolaris.org/os/community/zfs/).
