So the image of walls is an ....phor?

Actually an interesting proposal, mav. So the dia- or epi- of the metaphor can actually be malleable depending on
interpretation. You just created a new theory!...so you need a new --phor for it! (maviphor?) And here you thought you were just kidding! I guess life is too short to grok the difference between dia- and epi- when one's time is spent in such worthwhile endeavors as constructing whole alias networks of websites and bios, etc., etc...right, mav?
