Why?

Because 100 m Cat5 cabling is cheaper than 5 m of current SCSI cabling?

BTW, SCSI is used for lots more things than storage - my favourite
application was the one that used SCSI to control a laser rangefinder....

So write a laser rangefinder protocol over TCP, rip out the SCSI interface, and
put in Ethernet.  The silicon's cheaper, and you'll probably get better
performance by reducing the layers.  Alternatively, if you've got a legacy
device, attach it to a host running the laser rangefinder protocol in software
(which'll probably be easier to write than a generic SCSI bridge).  Only
problem is if you've got an existing laser rangefinder GUI that you want to run
remotely, and that you can't convert to use the new protocol.

The second most common SCSI application (after disk drives, for which we have
NFS) seems to be scanners, for which remote use doesn't make much sense; you
have to be physically at the scanner to put the paper in.

Mind you, if people want to work on this, I'll assume they have a use for it;
I'm just bemused.
