Dear Frank, you said:
I still don't see why it doesn't work in terms of the additional circle of position that you described.
What if we use your nice weapon just used against the "paralactic retardation"? Let's imagine those two bodies are on the same vertical, will it change the azimuths? Can we talk about azimuths (at all!) without assuming an observer's position first?
