This is really cool! (and Jon Udell rocks! – just between Jon Udell: A Google Maps walking tour of Keene, NH and associated posts and his work on the IT Conversations AudioClips function [more info here and here, implementation details here] he’s a web-interconnectivity powerhouse, and that’s not to mention any of his other work).
However, getting into the details uncovers that you have to have a special tool and specifically the Firefox browser (which you should have, but that’s another story). That’s much more complicated than what I hoped for.
I was thinking of hacking together a customized Google map of my rather byzantine route to work this morning, and I may still do so using this process. I’ll also look and see if I can find a way to do this without ignoring those other browsers.
