Oh - yes, the unobtainium rod thought experiment :)
Well - I guess that when you move an object - you firstly move (push away) - due to electromagnetic force the closest atoms first - which in turn push away the next... etc. until the whole object moves. I guess that what happens is actually an oscillation between atoms.
So you would notice the far end moving in the time a photon would take from one end to other - in best case scenario.
You know that information cannot travel faster than light? Even if you try to send it via wiggling of unobtainium rod :)
