[Openstack-operators] VM with a public IP

Have you tried to use public IP addresses in place of private ones, I mean
as fixed IPs? I'm just curious, because I have thought if something like
this could work, but actually haven't tried myself. If you check
https://trystack.org/ they have something similar working in production,
their Horizon lists the VMs IP as private (and it is the only IP the
instance gets assigned by default when spawning), but it's actually
publicly routable address. So somone who's involved in TryStack could shed
some light how they are doing it.
