Ken,
I�ve seen a laptop set up like you describe. I have a friend who is a 
regional trouble shooter mechanic for Mercedes Benz. He goes around from 
dealer to dealer fixing the cars that they cannot or will not. He gets a new 
MB company car every couple months to drive and to become familiar with the 
new models. One day he drove up in a SEL convertible with an IBM Think Pad 
laptop plugged into the cars computer with a special harness. With the laptop 
he could get every detail of what was going on in the engine-temp, RPM, CO 
content, oil pressure, everything. He said it was of particular value to him 
because it gave him specific details of engine operation when driving and 
under load. I�m sure it was an expensive little unit, but its been done, 
maybe it was put together with off the shelf parts/programs. I�ll ask him 
about it.
