Tell me the bad news.

             I may need up to 0.6 Terabytes in the largest system,
             as little as 50Gb in the smallest.  So - between 1 and ~12
             drives.  You can have 16 widgets on a SCSI bus - right?

             Dunno - this can go into a custom cabinet - so I imagine
             we can engineer that.

             That could be pretty scarey with 0.6 terabytes!
             I can mount the drives read-only though...maybe
             that'll prevent us from needing to fsck.

             I can boot and swap from a regular $100 IDE drive - so
             we don't have to worry about that.
