It depends on what you mean by "SCSI" and "very short".  SCSI-II allows for 
a 6 meter cable length in single ended installations; and 25 in differential.

I believe much less (3.0 meters rings a bell, but don't quote me) is 
allowed for in FAST20, UltraSCSI, or whatever they're now calling the 
20MHz (and proposed 40MHz) parallel standards.

In practice, yes.

IMHO, it would work very well for a Linux cluster/multi-computer,
multiple boxes in the same rack needing high-speed networking, and
network stack development.
