I can't remember if it was Cumana or SJ Research, but one of those
companies had a system where a disk was shared on a single SCSI bus
between multiple BBC Micros (or maybe Archimedes) and the bus was also
used as a sort of network between the computers. As I recall it, the
principle limitation in practice wasn't the obvious one of 8 devices on
a narrow SCSI bus, but how close together the machines had to be because
of the limited length you could make the bus.

Which reminds
me of a comment I saw somewhere about the possibility of
having
a SCSI bus with more than one host adapter on it. Is that even possible?
Absolutely...SCSI is a (mostly) peer-to-peer bus. You can easily set
up multiple "masters" ("initiators" in SCSI parlance) on a SCSI bus
if
the hardware implements the spec in a reasonable way and the OS' drivers
can do something useful with the capability.
Communication between host adapters is also possible; I'm sure I've
even heard of "IP over SCSI" having been implemented.
