Being able to specify an qemu-ifdown script is reasonable, since we already
support an qemu-ifup script, but I don't want to just add that without 
a clearer understanding of exactly what type of network config you are
trying to achieve. So rather than describing a desired implementation can
you describe the deployment scenario / level of network connectivity you're
trying to provide.
