Considering that a Mac connected to a SCSI device is just a SCSI device
itself, as far as the device is concerned, is there really any reason
that you couldn't simply daisy-chain two computers on a SCSI chain and
have both of them address the same disk drive the same way that one
computer can address two disk drives?  I'll admit I don't know how the
SCSI protocol works (and I'm sure it shows :-) but this doesn't sound
THAT impossible.
