I like retronyms, specifiying words to distinguish the general word from a more common specific one. I'm not explaining it very well, but the examples that leap to mind are "black-and-white television" (as opposed to "color"), "acoustic guitar" (as opposed to "electric"), and "snail mail" (as opposed to "e"). Crossing threads, perhaps we need to start using a retronym for "built architecture" or "bricks-and-mortar architecture" to distinguish it from the new-fangled computer kind (at least buildings won't be "architected" any time soon -- or at least I hope not!).
