What exactly is it doing?

Looks like it uses the usb redirection channel, correct?

Hmm, so it isn't only usb emulation, but also scsi emulation duplicated
in spice-client.  Why this route?  Wouldn't it be simpler to run nbd
over spice-chardev, then hook up the iso as blockdev in qemu?  Which
you then can attach to any cdrom emulation (ide/sata/scsi/usb) in qemu?
