Since we want grub use this module and at this point in time the FUSE
interface is more stable than grub interfaces I think it would be more
natural to start developing this kind of module with GRUB unless there
are some license issues. After all, grub includes other tools that are
meant for running outside of GRUB. The question remains who (if
anybody at all) writes the wrapper.
