Okay, what is it? It's called the Public Radio Roadtrip. It incorporates location-based-audio (or other media) and mapping. It doesn't aim to be a cms. It allows media organizations to continue to use the publication tools of their choice. However, it provides an "editorial layer" between disparate web sites (or apis) and it leverages the power of geolocating stories.
I've been working on this app for almost a year now.

You can try out the demo here: http://publicradioroadtrip.appspot.com/publicradioroadtrip/
I've blogged a bit about the concepts and ideas behind the app here:

I've had significant input from practicing journalists and technologists from within public media such as Krissy Clarke at KQED, Javaun Moradi at NPR and Barrett Golding (at Hearing Voices).
I think this app has a lot of potential to grow in the coming year. I envision ways where journalists and citizens could inform the direction for the creation of this app. I envision ways where this app could be a useful tool for journalists working to define and discover ways in which location based stories are concieved and told. And I think this could be useful in promoting Mozilla's goal of openness, standards and innovation.
Thank you for your consideration.
