AFAIK, the policy is "if I don't step on your feet, and you don't step on
mine, everything will work okay."

I have two boxes which share a tape drive with no problems.  Of course,
they _never_ try to use it at the same time... I remember having both
access it at the same time, and the result was a bunch of SCSI errors and
one hung machine :-(

It would be neat to be able to have a machine mount some SCSI disks as
r/w, then have a few other machines mount them r/o, but I think there are
caching issues with this right now.
