I've looked at doing something similar on and off for a long time, but never really got beyond the basic ioctl proof of concept stage. Since it appears ata and atacontrol might be replaced by CAM, and SCSI devices can also support SMART, would it be possible to add this to camcontrol or a similar utility?
