I think they're pretty close, but you'd have to ask someone who has actually compared the drafts to the standards to be sure. :) FWIW, we have used the drafts for the CAM development, and I don't think we've run into any issues caused by a draft/standard difference. What sort of emulator are you working on? Is this a SCSI target emulator, i.e. something that is supposed to act like a disk or a tape drive? Or is this some other sort of emulator? A well written disk emulator (or tape emulator) could be a valuable contribution to FreeBSD. You could use a disk emulator to do things like form the basis of a FreeBSD-hosted software RAID array, or to test error recovery code.
