Thanks for sharing, I’ve been meaning to check out what some of the other projects have been doing with this. I actually just started prototyping some ideas for a “data source” system for plugging in other formats. I’m hoping to have this system in place by the start of Google Summer of Code, to make it easier for applicants to implement client-side support for KML and many other formats.
