   I agree.  But even in the current world, SCSI doesn't *need* much 
improving, except for maybe dropping the cost...which is a business 
problem, not a technical one.

   Improve on Ultra320?  Drive mechanics & media can't touch that 
transfer rate as it is; the headroom is there to support multiple 
drives per bus.  Need even more than that?  Think FibreChannel...SCSI 
protocols over an ultra-high-speed transport.

   Well, there's FibreChannel...
