I would recommend first writing a SCSI MIG protocol, so that you can write
generic SCSI-MIG disk, tape, CDROM, scanner, etc. drivers which then talk
SCSI-MIG commands to your SCSI driver.  Every UNIX I've seen that
supports SCSI has a multiplexor like this, but the mux is ad hoc and 
difficult to re-use for funky devices like scanners.  

Or networks: SCSI is several times faster than Ethernet, 
and makes a a great IP transport for a few computers close together.

Mach 3.0 needs an official SCSI MIG protocol.
