this would be some monumental undertaking - since the real idrive is using fiber-optic, one would need to have gazillion converters from copper wire to optic, besides the micro-controllers to interpret the ibus protocol into most protocol.. the system will be sluggish, as it takes time (and power) to translate a message from native ibus modules to the most and back... the whole car's electronics would need to be redesigned, and without the r&d support of a large construction/engineering firm this will be a royal flop...

but... i could be totally wrong...
