I'd love something like this...perhaps an install mode for mapping CAN commands would be in order for a more complete integration of a linuxmce box into a car. I would probably only want to make the investment if putting a box in the car if it was totally tied in and CAN-USB adapters allow you to use your existing controls to achieve just this. For those that don't know CAN stands for controller area network and is a protocol standard implemented in most newer vehicles. It allows the electronic devices to talk to eachother over the CAN protocol for controlling/monitoring external devices. I believe this would be a nice addition to the already powerful IO device support of LMCE. There is an open-source project called cPOS that is doing exactly this, although it's not very straightforward to setup, it does indeed work and their code is available to any developer who might be interested.
