If you use the chain-driven Nano Tube setup, this is a non-issue (just move one of the chains to the other pair of shafts). With gears, I could see it being a bigger deal - but still, for a skid-steer (6WD) setup, I would want to chain the other shaft to the two geared ones anyhow. This allows for all of your motors' power to be transferred to the floor regardless of which wheels are in contact. We are running the chain-driven Nano Tube with two chains per side to connect all of the wheels (we are using the longer Nano shafts and cutting off the excess to give us more space to mount two sprockets and a wheel to the shafts).

Though purely from an aesthetic point of view, left- and right-handed Nano Tubes would be sweet!
