Well, this guy has a stock 2.5 V6 with considerably less torque than a modified JTD like yours, and certainly more "linear" power output as a N/A engine. The roads where he tested the diff are very slippery, i can assure you of that, but there wasn't any ice because the outside temp is still well above 5 degrees in Athens. IMO nothing can save you from an ice patch if BOTH tractive wheels hit it, apart from tires with spikes of course.
