It's not impossible, just hard(tm). You need to export a fake/virtual mass
storage + FAT device over the USB; dynamically mapping blocks as requested.
The read/write requests are parsed as they come in and mapped to normal file
accesses; all the hard work should already be done as it's used in the QEMU
virtual FAT driver.
Why do one side of a triangle when you can do all three. Somewhere, GB.
