I'm helping to test out the new Platial MapKit that's in development, and so I thought I'd map out where DEMO 07 participating companies came from - please feel free to add to the map! (Disclosure note: I manage Omidyar Network's investment in Platial.) I've just added a few from the book, but others are entirely welcome to add themselves. Just remember that it's a live test of development software. ;)
