I do agree.

bertagaz and I have spent a bit more time testing and comparing the
available options. Our results are summed up there:

tl;dr --> as far as Wheezy is concerned:
  * qemu-kvm emulates just fine a USB 2.0 mass storage device, and
    knows how to boot from it; personally, I'd rather use that than
    a dedicated kernel module.
  * with qemu-kvm on the command-line: no need for an additional
    kernel module
  * with a libvirt stack: a missing interface in some abstraction
    layer makes it a pain to use the qemu-kvm USB emulation of
    removable mass storage devices.

We are going to request the missing interface to upstream libvirt,
but it's unlikely the result thereof is ready in time for Wheezy.

So, with my Tails developer hat, we would be happy to use
g_mass_storage at least from now to the Wheezy+1 release.

I'd be interested too!

Cc'ing the Debian Live mailing-list, as there may be folks there who
have experience on this topic.

Perhaps debian-boot and/or debian-installer should be added to the mix
as well, what do you think?
