Cars are getting more computer systems, and those systems need to talk to each other. To manage this electronic chatter, BMW R&D is reportedly now using IP -- the same protocol used to move bits around on the Internet. Looking at it another way, each of these BMWs has its own private Internet inside. (props to Autoblog)

I think the term you meant was intranet, not Internet.
Also, this is hardly news. BMW has been using a CAN-BUS a distributed control network using a communications protocol similar to TCP-IP in it's cars for years. CAN-BUS was first used in high end cars in 1992 and is not used in just about all cars nowadays.
You're right in that it's nothing special to have an in-car network. What IS special is that they're moving from a closed industry standard to something more universal like IP. Hopefully they use standard Ethernet at the physical layer, but even if they don't it's only a physical layer adapter that's required before we can talk to the car using a standard IP stack. We're just one hacker away from slapping a wireless interface into the in-car network so we can play our wi-fi enabled media player through the car's speakers and on the rear-seat monitors. Convergence is a happy good thing :)
well, you gotta remember that the CAN ISO protocal has been standardized for automotive use for diagnostic purposes, all manufactures use the same protocol. and in fact, every car sold in north America starting in 2008 HAS to be CAN per gov. its possible that the different manufactures can run different protocols on the main bus, and sub layer busses, but the diagnostic bus has to be to ISO standards, its basically like how obd2 came into effect, there was a 3-4 model year window they could switch to obd2, then by 96 all cars were obd2. same with CAN, they could start switching the diagnostic bus to CAN in 04, by 08, all cars.
