[OpenLayers-Dev] multiple maps and one panzoom control?

a control is associated with a single map (by adding the control to  
the map) so what you want is not directly possible.  However, it would  
be easy to fake it by adding an event listener on the map that has the  
control and programmatically setting the center and zoom of the other  

window.onload = function() {
     map1.events.register('moveend', null, synchronizeMaps);

function synchronizeMaps() {
     map2.setCenter(map1.getCenter(), map1.getZoom());

If you wanted some offset in zoom level or something then you could do  
that in synchronizeMaps.  If you actually want the maps to be at two  
different starting points, then you can adjust the center by the  
difference as well.
