 for the software inteface, I would think, since there are scsi stacks
 that can target devices available on most platforms. 
For hard drives, probaby.
For looking at alien FLOPPIES, I don't want ABSTRACTION past cylinder,
head, and sector!
  IDE could be supported for drives with 512 byte
sectors as well, since
 its format is so close to scsi. 
I wouldn't know.  IDE is based on ST506/412, with its INT13h access.
But,
whatever works for you!
