I think you are missing the prior commentor's point. MITM already has a specific definition. It isn't as broad as you are attempting to redefine it. This concept is commonly understood by security people and commonly confused by software developers. I suspect the failure is that for software developers all parts of a network are in the middle between their application and their end user, so anything in that nebulous space corresponds with the words comprising MITM. That line of thinking is reductio ad nausium.
