You need to start studying up on off road racing, because transaxles and center diff sections in multiple classes of baja racing and Ultra 4 Unlimited class racing (King of the Hammers) not only have vehicles that run 300-800(+) horsepower, but they also have as much as 28" of wheel travel and have a track width that is the same or not that much wider than my full width solid 1 ton axle JK.
Dynatrac IFS will work in any of these race cars that have two to three times the suspension travel of your Jeep

I think you missed the point. All I was saying was it is one thing to make a reliable IFS drivetrain setup in the rear of a sports car with a few inches of travel vs a Jeep front end with 10"+ of travel and that has to deal with steering much less the rigs you point out with much more extreme circumstances.
I didn't say it has never been done or is not possible, but looking at it from a commercially viable standpoint where companies have to look at costs vs liability exposure, it is going to be more difficult and limiting than the IFS setups in sports cars for both OEM's and aftermarket manufacturers such as Dynatrac. The physics dictate that as the driveline angles become more extreme, the more stress you are putting on the joints. And the geometry would have to be steeper because as opposed to the Baja/KOH style rigs there is not nearly the ability to setup such long A-arms in a factory street vehicle.
Now the Ford Raptors have gotten a pretty darn good setup and straight off the floor they ride great on the road and do very well in the bumps and have pretty decent articulation. But they do come at a price which is going to be difficult to justify for the run of the mill Jeep Wrangler that spends its life doing mall duty. Look at even the current Mustangs (I know the new model is going to IFS), costs dictate that they still utilize solid axle technology. All of this talk and rumors of a 2016 IFS Jeep over the past month or so I believe are just that for now. At this point of the design, Jeep would have long ago already locked in such an important design change. I could be completely wrong, but I would guess they are floating the idea out now to judge feedback and feasibility for the following Wrangler iteration that would bow sometime in the 2020's when CAFE standards dictate huge increases in fleet efficiency.
