So at a quick look I have found fuseext2, fuseiso and mountlo-0.5 (which
claims to have supported all the in-kernel filesystems with the help of
user mode linux).

Give that the first two are just an apt-get install away fuse really
looks like the shortest path to being able to mount an iso, do other
interesting things.

We probably want something more but only when performance becomes a
bottle-neck.
