I see the v1.1 API spec talks about a 'hostId' item returned when you list your instances (section 4.1.1 in the spec).  These should be the same thing, IMO.

I think you're right, though.  I don't believe we have any sort of 'hostId' today, since hosts just become available by attaching to AMQP.

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).
