so as the cororally how does one put multiple tgz files on the tape? by
using /dev/nst0? then just write tar after tar until the tape is full?
other than not rewinding what is the (dis)advantage of using the rewinding
device over the non-rewinding device?

no these are all scsi devices that are being used.

i was reading that man page earlier, is it really necessary to rewind it?
basically once the tar files have been written to the tape it will be shipping
to my client's client who will load the tar files onto their unix boxes, (sco I
think). How does one controll how far to rewind? does the h/w know that?
(speaking about scsi dat drives here, specifically the hp units)
