Sounds like something usefull. This device can be the thing to fill the gap between floppys and whdload.
Wasn't there a design from jim brain for the C64 that used compact flash and could connect to the normal serial floppy port of C64. I can imagine it is the same idea but that this device is able to emulate the amiga floppy interface.
