Alternatively, can I write the same data to both drives such that I
create a duplicate tape set (one to keep on site, one to send off ?).

You can setup RAIT:
http://www.amanda.org/docs/rait.html
http://wiki.zmanda.com/index.php/How_To:Set_Up_RAIT_(Redundant_Array_of_Independent_Tapes)

But currently only 3 or 5 drive sets are supported.

2 drives is also supported, and that is a mirror.

I'm not looking to do RAIT, unless there's a RAIT-mirror option.

ok, so that you can do.

I could, I suppose, have a second set of tapes in the library, and
when amdump finishes, run dd from one tape to another, but it would
seem to be preferable to write the data once to both drives
simultaneously (i.e. mirrored tapes).  That doesn't sound possible
though.

Mirrored tapes do work.

Read the wiki page mentioned above.
