But the machinery basically has a tape emulation module (sim_tape.c) which has a number of functions roughly corresponding to what a tape drive does (read forward, write tape mark, rewind, etc.).  It doesn't look like a terribly hard task to support a real tape drive as another "container file format".  One question I can think of is how OS-dependent raw SCSI access is.

RAW disk does that also includes using a zfs/fc/iscsi volume as disk ?
It should considering they appear as sd{a-z} on the host.
