Yep. The hard part about this is that even with host headers is that
we don't know which backends to send requests to. We need a load
balancer service that acts as a reverse proxy. Of course, we don't
really want to write this ourselves. Thankfully, there's a proof of
concept openstack service for this as a component of quantum. I
believe HAProxy is one of the first supported services. It's likely
not acting as a proxy, but we can probably write a plugin to make this
work.
