.app files on the mac don't take options from the command line the way that windows exe files do. you may have more luck sending an "open document" appleevent to the .app with those parameters. you might google around a bit to see if anyone has tried this.

This is awesome piece of code.

I can control in real-time the navigation of google earth.
