Linux, open sores, and questions of a technical nature are all on topic for
the main list.

I don't know if you can present a Linux block device back out a SCSI
controller... the closest thing I know of that you can do this with is
i-scsi, i.e. present the block device over the network. I haven't actually
done anything with i-scsi though, so can't help you further.

AMANDA ( http://amanda.org ) has support for what it calls vtapes, i.e.
using a set of directories in place of physical tape. There's plenty of
howtos on the website on setting it up.
