Well, the way you put it, applications would interact with the periphery at a pretty low level.  That is not the case.

It's a continuous coordinate system, with 0,0 being the top left (or was it top bottom?) of the main screen (the one where the menu bar is).   You can simply specify 'top and 'left with pixel values as frame parameters for the new frame, and it will open in the desired position.

Aquamacs also has Emacs functions that will tell you the available screen areas (excluding the Dock, etc) - see `display-usable-bounds'.  You need to identify the screen via an existing frame handle, though.  See also `display-screens'
