There's some interest from people doing vfs maintenance work (as it has
potential to save their work) and it is actually a reasonable task for
someone wanting to get acquainted with filesystem development work. So I
think there are chances of some progress. For example there was some
interest in doing this for minix. Of course we'll be sure only when it
happens :)

Full VFS emulator would be too much I think. Maybe some helper library to
ease some tasks would be useful but I think time for comming up with
libraries is when someone commits to actually doing some conversion.
