Both are packet based protocols with almost exactly the same commands. I worked with Jens Axboe <cdrom maintainer for the linux kernel> a bit trying to figure out some strange behavior or the ATAPI drivers. The stuff that didn't work in raw ATAPI the way it should in any linux kernel after 2.2.14 suddenly worked when SCSI emulation was enabled. But I still have to say that since burncd works so well I have no inclination <or time> to write such a layer for FBSD.
