not really. if you enumerate a volume (i think) then you can fmt it and get
fat/ntfs to mount on top of it. as long as you redirect the i/o to the
right offset in your file, this should work at a low level.

Thats great. Actually what I want to achieve is this:
A virtual device that will appear as a harddisk to the user. But the disk
actually maps to a filesystem in a single file (more like a filesystem
within
the operating system's filesystem - eg: AidAim FS). Like GoogleDrive,
except
for the fact that the files will be stored locally in a single file.
I guess I will have to write a full file-system driver + a harddisk
emulation driver. Am I right in assuming this ?
