	Thanks for bringing this up.

	As the case hasn't started SAC review and the changes seem
	to be confined at the implementation level rather than a change
	in the primary architecture, here's what I suggest:

	1) update the spec as you suggested.  Keeping around the previous
	   spec just for reference.
	2) make the interface changes in the the opinion interface table.
	3) add a section 4 paragraph noting that when implementing
	   the TCR that some of the interfaces changes to accomodate
	   the implementation and they are reflected in the interface
	   table and updated spec.  And some short comment that the
	   specific change was: something like to change the abstract
	   slots to host driver devinfo nodes and why.

	4) Send this on to SAC review.  Set the timer for a week
	   and in the note around the SAC review make a short statement
	   about what changed, why and where in the opinion that change
	   is reflected.
