It does look very promising - its definitely something we should try to
make use of in virt-install as it ought to make us more robust wrt to
future changes. If anyone's interested in supplying patches to make use of
the .treeinfo files, please send them to the list, otherwise we'll consider 
this a TODO item for our development roadmap.
