I'm not talking about the specific implementation, but about the
general design.

WhyzzyTeX + ADvi shows you a cursor in the DVI output which tracks the
location of the cursor in the Emacs buffer, and if you click on the DVI
screen, point is moved to the corresponding source location.  It's not
perfect, but that's a detail of the implementation: after all, TeX was not
designed for interactive use.
