Again, in the olpcfs design we provide a vfat-like metadata structure
(mounted via FUSE) so that the filesystem on the USB key appears to
the journal code just like the flash does.  No FUSE is necessary to
see the files on the Windows box, although if you want to see all the
metadata then you need some tool.  If you're transferring the file to
another XO, then the metadata comes along with you.

I'll write this up properly on the Olpcfs page so I don't have to keep
repeating it.
