where can I find info on AS/NZS 4270? Is this an adoption or SDTS or just
something similar?  What about ISO? Is there an ISO committee looking at SDTS?
(which committee? who is taking the lead?)

A group that I am involved with is beginning the standards process
for agriculturally-related data (mostly with respect to precision
farming). We are leaning heavily toward SDTS as a short term solution
for static data interchange. (Thus my questions.)

To make this a grass-specific message, some may be interested in 
knowing that SDTS is used as an export format on a web server
(grass commands are dynamically executed to created a vector profile):

BTW, anyone have any target dates for grass implementation of the
raster profile?
