Yep. John Jackson has created a "tapeio" branch of the amanda-242 code
that basically treats a directory as though it is a tape. You'll need to
get that code from the CVS repository.
The announcement of the tapeio code and a good description is available:
http://groups.yahoo.com/group/amanda-hackers/message/2518
The ensuing discussion is also archived:

I would expect that you could create mount points for your removable disks
and use those mount points as "slots" for a changer script (there's an example in
the announcement). You could either ensure that the proper disks were
inserted and mounted before each run or hack on the changer (chg-multi,
chg-manual, etc.) to do whatever is necessary to get the proper disk pack in
place.
Hope this helps,
-Ben
