--verbose please.

Sure.

Yes, but for compensation you can drop code emulating usb-storage and
scsi spice-gtk.

Yes.  But why is this a problem?  If the user can share one (or maybe
two for both installer and driver) iso images, having that many cdrom
drives in the guest should not cause much confusion, no?

So you trade short-term simplification (only spice client update
needed) over long-term maintainance requirements (all the additional
usb/scsi emulation code in spice-gtk).  I don't think this is a good
idea.

cheers,
