It's about a 40 line program to prompt for a source diskette, open a floppy,
malloc() the appropriate amount of memory, read() the whole thing and
then loop prompting for destination diskettes if you hard-code the
device name and size.

You can probably do just about as well just using cp or dd to copy in
a master disk to a file, then back out again.  Just be sure to use
the character device for the size floppy you want.  You can even use
zcat >device if you want to compress the image files, and wrap a
shell script around it so anyone can do it. 

For 100's of sets, that is probably the best way.  For 1000's you will
want to have a service company do it.
