Someone already made something similar: http://software.intel.com/en-us/articles/where-is-my-car-web-app-and-phonegap-app
At this point I’m looking for a good cordova.js stub file – seems others are also looking for something like that but there aren’t any to be found in the small search I’ve made – only the Ripple chrome extension which only supports Cordova 2.0 and didn’t really work all that well with my basic App. If I wont find a cordova.js stub I’ll create it myself.
