There is no intent to modify the OS. There is possibility to modify core libraries on jailbroken iPhone using LD_PRELOAD functionality to hook some functions. But this is not a good option.
There are some tasks, like automatic integration of car sound system with iPhone, or interaction with music player/receiving calls while driving. I see no possibility to achieve this without remote control. The remote control may be implemented as set of named "buttons"(play,stop,send list of songs) - just like multimedia keyboard keys

No way, not ever.
You can write an app that allows remote control by a car, throught whatever interface you support.
This is a user-to-user support forum. There are no Apple engineers here. They are very easy to contact. Just open a developer support ticket.
