This is a tricky one.

 

  1.   I would create a popup window or an IFRAME with a map inside. 
  2. The map I would use is an OpenLayers.org map. 
  3. I would set up event hooking in the MAIN map with http://trac.osgeo.org/mapguide/wiki/CodeSamples/JavaScript/AJAXViewerEventHooking to watch the map and send extents to the overview map.
  4. If you wanted to get really tricky, you can draw a box using the OpenLayers.org API using the extents sent from step 3.
