If your AJAX webmap client of choice happens to be OpenLayers, there are
better ways to do this.
Assuming you don't want the whole world labeled, you might consider
using a WFS layer instead of a WMS layer. Then you can use OpenLayers to
create *real* vector layers that can even have effects such as light up
or resize *and* make the mouse cursor change when moving over a label or
object. Plus it will give you the option to open up pop-up balloons,
something you will hardly get done using a raster-layer only.
Otherwise, you are in there on your own. Your ajax script would need to
translate real coordinates to pixel coordinates, guess label coordinates
and stuff.. I would not go there if I where you.

Hi folks,
Is there a way to get back the exact position of the labels in a
MapServer map? I want to make the labels clickable with Ajax, so a x-y
values in image coordinates would be enough. I looked in the Template
and Mapscript docs, but couldn't find anything about the (computed)
position of labels.
