I wonder if blkfront could register itself with the scsi subsystem
rather than directly as a block device?
I bet that would mean it would have to deal with SCSI command blocks
and stuff, so I doubt it.

Well, random ide/ata devices are now part of scsi via libata, and they presumably can not deal with raw scsi commands.
