However, you're addressing the nodes on the chain as mass media entities,
not network interfaces -- unless you also intend to have host-host
communication devices (which should have their own device attachment into
the standard NetBSD network subsystem, of course).

But in this case DSSI is not part of the NetBSD *network interface*
subsystem.  USB and SCSI are also examples of networking systems with
different underlying link protocols, but neither is inherently a network
interface from NetBSD's point of view.
