I'm just looking for a way for this to be something where I can point someone and say: "click here foe a site that has an alternate player app for the Empeg Car and it has all of the necessary installation instructions etc."

Does the author of RioPlay intend to support the car player in this fashion, or do we need this project turned over to someone who wants to continue it?

I based that on your statement: however since I'm quite done with our end of things...

Unless of course, you meant to say "not quite done", in which case I withdraw what I said and I eagerly await a site where everyone can go to get the app with installation instructions.
