If I'm not mistaken, SCSI-3 isn't even a spec yet.  Some vendors are
implementing bits of the draft spec, but they haven't even come close
to the real thing.  An article I read a couple of years ago talking
about SCSI-3 features mentioned stuff like 120 devices on a chain,
100+ MB/sec transfers, etc.  Of course, before it actually hits "for
real", we may have FireWire (IEEE-1394) or Fibre Channel...
