Does it have to be Amiga specific?
That was kinda my hope. Something I have half a handle on.
I just want to try an idea I have been waiting for someone else to implement, but which has never happened. The FS and Amiga interface should to be as simple and clean as possible to make it easy to make changes and try it out.
The FS can be as rudimentary as you like as long as I can read and write files to the mounted volume.
