Maybe I'm confused; it's been a while. I thought that AoE was ATA over
Ethernet or something like that, and that ATA was basically the SCSI
protocol over different electronics. I was originally looking at this
in terms of a digital camera that connected via USB, which did speak
SCSI. Regardless, the salient point was that there should some way to
hook into the devsd framework from userland.
