I found a list of T10 activities just since just Dec. 1, 2008 and it
is a bit overwhelming.  (ie. 08-356r4 is but one of many recent
reports)

http://www.t10.org/new_a.htm

For those of us that don't live and breath the SCSI spec, is there an
overview site describing what is going on.

Maybe:
09-059r0 	T10 Project Summary - January 2009 	John Lohmeyer 	PDF
(34729)	2009/01/22
http://www.t10.org/cgi-bin/ac.pl?t=d&f=09-059r0.pdf

I have not read any of the Post Dec. 1 stuff including the above
project summary, but based on the names these seem potentially
relevant:
