Terrific Post. I'm going to need to reread it before I comment much as you present a whole lot of information in a small space.
I would think, though, that instead of a flat map, maybe we mape the positions onto a curved space as the slice of an elipse? This would provide some spatial information, would work well with the current location at the center of the slice and would represent a better simulation of how humans hear in the forward direction. Also, some 3D plotting will be necessary so as to "project" the map image some bit of distance in front of the userso it floats in space like a heads up display on a airplane or some automobiles. We're in house guest mode so my response further may take some time but I think you are onto something really cool.
