Nice setup by the way. I too have an E46 M3 SMG2 in the Uk and am currently doing something similar. Did you ever manager to write that software you were talking about, i.e. that mapped the 9600E81 Ibus to specific keys, with a small ini file you could make those buttons do anything. That would just be cool. Also out of interest how do you hibernate the PC etc, as I say I am new to this!
