Flashearth we can run with parameters:
http://www.flashearth.com/flash_earth.swf?lat=43.3&lon=5.5&z=7.2&r=0

Barry can adapt script:
http://www.nearby.org.uk/google/flashearth.kml.php?
to call of coordinates and uses BBOX from network link for calculation of parameters. This construction can return map in actual view maybe?
