Right so we should really be hashing this with the tenant ID as well.

I've proposed a blueprint and spec for a /hosts admin API resource that would return information on physical hosts. However, I don't believe that there's any way for us to actually identify a specific server (I'm actually hoping I'm mistaken about this, because that would make my life easier).
