Hacking SVG into Google Maps

This morning Ruud Steltenpool pointed me to a cool post on Jibbering where the author hacks in SVG support in the new beta version of Mozilla in Google Maps:

"The Google Maps API uses VML in Internet Explorer for drawing polylines over the top of the map - for directions etc. In the other supported browsers though, it renders transparent pngs on the server, so a higher bandwidth load, and not so neat for the user. SVG shares a lot in common with VML, so I decided to see if I could hack SVG support into the Google Maps API code in the SVG Enabled Deer Park."
