Any SCSI gurus listening in?

I'd like to cast a vote in favor of making it easier to specify host SCSI id's.

For one thing, some workstation firmwares let you set the host SCSI id
to be used when booting. It would be nice if we could respect this somehow.

Every now and then people make noise about supporting SCSI networking,
for systems that have SCSI but no useful ethernet. Easy setting of host
SCSI id's is essential for some applications of this.

There used to be a product for the Apple II (believe it or not) where you
could connect 7 computers up to one SCSI drive. Usually each machine had a
distinct writable partition, and you could set up partitions that were
read-only to all machines. It'd be cool to bring this back on NetBSD.
