Default Siri Eyes Free Proxy for Android - Does it exist?

For those of you that haven't heard, Siri Eyes Free is Apple's iPhone intergration with select Honda and Chevy cars.

What happens is that the car's interior microphone and the steering wheel voice button both act as a proxy to funnel input to the phone over bluetooth.

Did anyone hack together an Android app to work with iOS's input api? All I really want is to send text messages / initiate calls using google now voice.

I could get an iphone for testing. I have a laptop and a phone with bluetooth, if those can record the raw bluetooth signal
