Great summary, Bill. Also, as I think I maybe pointed out in that thread, there are AC units intended for windows and those that look very similar but are intended for walls. I've never looked into it to get the specifics, but I suspect the vents are in different spots -- in a wall unit, for example, the sides are likely enclosed on the wall, making side vents ineffective. So maybe a wall unit would be easier to direct that hot air outside, I don't know, but just thought I'd throw that out there.
