The way I see it :

1.- The vinculum chip handles accesses to files in a single FAT
filesystem volume in a single USB mass-storage device.
2.- Some (disk image) file(s) in the FAT volume have to be mapped as
physical volume(s) to the Apple II.
3.- In a pseudisk-like way, an AVR would take care of the abstraction
files-> physical volumes.
4.- Here there's not an AVR, so unless the vinculum can handle this,
the Apple II will have to do it.
