KML -> KML Tour Conversion and Player for Google Earth JS Widget

I have a website where I currently display KML map data using a variety of ways. I'd like to build out a 3D Tour Viewer as an option to display the map data. I would like the following functionality: 1) Form where I can enter a URL to an existing KML file ie, | KML URL: | __________*text field*_________________ | | | [Submit Button] | An example of a KML file I would use is: [login to view URL] 2) Have the form submit to a PHP file that converts the KML into a KML Tour and allows it to be played in a viewer similar to [login to view URL] ie., when i submit a KML URL, I'll be on a page where I can hit 'Play' , and have the Google Earth player tour the route I submitted. I'd like this programmed, tested, and delivered within 7 days of acceptance of this bid. -Kevin
