I could - but it would be a worse hack (IMO).  I just ran a few tests
and surprisingly, routed vifs work, however the IP for the VIF must be
set in qemu-ifup and not in the custom vif script.  Forgive my
ignorance of what goes on "behind the curtain" but it seems to me that
not being able to override qemu-ifup (i.e. specifying a script to be
run instead of qemu-ifup) is the hangup here.  So the only way I could
use straight VIFs with no bridge is if I put a bunch of 'case'
statements for each vif/IP in qemu-ifup which will break my
provisioning model a bit; it would be easier to use bridges with the
aforementioned hack.  Should this be revisited in development or am I
way off base here?
