You'd have to loop through your markers, using .distanceFrom() to look
for the one that's nearest the chosen point, then call
GEvent.reigger(marker,"click") on it.
The big problem with that is that you're loading your markers with
GGeoXml, and that doesn't expose the markers that it adds to your map,
so you'd either have to switch to using a third party KML renderer that
does expose the markers, or listen for the marker .addOverlay()s, see
http://econym.org.uk/gmap/interceptor.htm which is trickier and not
futureproof.
