Couldn't this be solved beautifully and in a generic way with some kind of
virtual SCSI adapter as a kernel driver, acting as a SCSIbus -> IP ->
SCSIbus bridge?
Maybe this isn't even possible in reality, I don't know that much about
the technicality around raid and SCSI-drivers... but you should be able to
write such a SCSI driver that could restrict reads and writes any way you
want... for example if you want to make reads local, but writes global, as
someone asked later in this thread.
Just a silly thought...
