That sounds cool, but I wonder about whether or not it's necessary.
Presumably for an existing legacy distro (like FC4), all that is
needed for xvd support are some udev rules, is that right?  In that
case, why not just standardize on xvd for new distros and install some
udev rules for legacy distros?

Is there another benefit to having a low-level SCSI driver that I'm
missing?

It could give us a framework for handling things like removable media better. Another, more bespoke, strategy is to develop that side of things further using xenbus as the signalling mechanism.
