Looking at the backend (LBCAS) that is the actually interesting part: Is
there any reason you implemented this as FUSE plugin?

I was thinking of implementing something like this myself for SUSE
Studio and figured the best way to do it would be to make it a qemu
block driver backend, en par with the "posix-raw" one. That way you
wouldn't need FUSE to download images on demand and also enable this
features for say Windows users.

So is there any plan on your side to write something like this for
upstream Qemu? If not that's fine too, I just need to know if I'd have
to do it myself :-).
