Gotta say,
I've been really enjoying this thread.
It reminds me of a very spirited discussion on Talkbass I participated in some years ago with the blasphemous title/thesis "The Myth of Modes" (which I attacked with quite a bit of vigor).
At some point I brought up sus chords and was challenged by a prominent jazz musician regarding my interpretation.
Managed to dig it up. The sus chord discussion begins on page 15 if anyone is interested...
