I have been looking at doing the samething with Hal in my car. I have come across several nice car PC's and most have more then enough power to run HAL and several other programs. This one is a indash car PC that i am looking at http://www.xenarc.com/product/cp-id8.html. I would also like to setup my car with a blue tooth device so i can talk with the car for startup and for opening the doors remotely.
