	Has anyone had any experience with WORM (write-once optical disks)
drives ? Please mail me.

	Since you can buy a SCSI drive for $4000 and a SCSI controller for
$1500 or less, I assume a major bottleneck is the non-trivial software
interface, i.e. how to make a write-once device useful. Does anyone have
any thoughts as to the "proper" approach to allow "transparent" filesystem-
like access, especially under UNIX ? It seems to me that a fileserver
daemon could be written to emulate a UNIX filesystem and hide the inherent
issues of the WORM...
