There are commands in the scsi spec to allow this to work.  However I have
never seen it done.  In Therory you could use the same set up to network
the two cpu's together.  We have talked about doing a scsi network (just
for fun) but we have not had time.

All of the existing drivers that I have seen specificly exclude this kind
of operation.

good luck.
