It has been done. We did it on a proprietry system with an in-house
operating system. Basically the whole thing was a
multi-processor/multi-tasking message passing system. We had a whole
rack of VME processor boards talking via the SCSI bus. The guys doing
the SCSI drivers somehow (dunno how) jiggered the SCSI stuff to allow
more than 7 targets on the bus (something to do with the arbitration).
All the tasks on the system just received messages processed them and,
if required, passed them on. The same thing should be able to be done
for Unix, you should be able to graft it on to the networking stuff at
the transport layer level (says he off the cuff.... :-)
