Many thanks, I will look into this.  I don't understand why SCSI 
RESERVE/RELEASE can't be used as the locking mechanism though.  Call me 
stupid, but I'm only a student.

As an aside, can you (or anyone) see even the *vaguest* possible use for 
my project?  It basically allows you to construct a "virtual" switching 
fabric with an arbitrary topology, attach a few fake disks to it, then 
load an LLD on various hosts and they all see all the fake disks.
