FWIW, I've done a lot of work over the years on my livecd creation
project (viros.org), and the main reason I worked on it instead of
solely on livecd-creator was a strong personal preference on not
requiring root.  My method for succeeding involves using qemu/kvm
appliances running just from a highly customized fedora-based
initrd-only system.  The result is that it is 6 odd times slower than
livecd-creator, but it doesn't require root.  Thinking about the
pre/post-inst rpm scripts being run under the limited protection of a
chroot in livecd-creator just doesn't sit well with me.

So it's definitely doable, but there is a price to pay.  Several aspects
that necessitated needing virtualization may now be doable via the fact
that fuse is enabled by default for users.  But I think there are still
a few places you need root (virtualized or not, but not just fakeroot)
to get the job done.
