Just a bit on the odds: i've blown exactly one SCSI fuse in my life
(*smirk* and it was on a sun) and i plug in/unplug SCSI devices from
live hardware not meant for "hot swapping" about 2x a day, on average.
I.e. you _can_ blow SCSI fuses, but i've had it happen exactly _once_
(and i did something bad then, anyway...  8-).

And then, there's hardware (e.g. DEC StorageWorks modules, of which i
happen to have one on my desk 8-) which facilitates and is built for it...
