Mark,
Is that SAT interface at the physical transport accessible
to something like smartmontools?

"SAT 0.9 transport layer" does not correspond to any t10 numbering.
Is the "0.9" meant to imply that the implementation is just
shy of compliance to the SAT-1 standard? [Perhaps a version
descriptor in the INQUIRY response answers my question.]
