Well, there's always sshfs:

If you're stuck emulating windows and you don't mind it being A) read only, B) 
horribly inefficient, you can try the virtual FAT support:

  http://www.nongnu.org/qemu/qemu-doc.html#SEC25

Note that's got some serious rough edges.  Specifically, if you _don't_ mount 
that read only, and your kernel accidentally tries to write to it, the device 
behaves badly.  (My emulated linux kernel went into an endless loop due to a 
dropped interrupt or some such.  No idea what windows would do, I haven't got 
one..)
