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