I thought about creating a plugin myself but really I have been away from car computing for quite a while and am just starting to get a little bit of the carpc bug back.
Anyway, this is a very interesting idea and definitely could be very usefull.
Vote do have your opinion heard.

If no one is interested in coding this I may do it in the future. But for now just generating some interest and hopefully sparking a developer to do this.
