I am a landowner/farmer and I would love to have one, and could justify the cost.
For me, I would attach it to my Wallenstein Log Trailer. In that manner it would propel my log trailer in a tracked, articulated sort of way, but allow me to have a bucket on the front, then my dump trailer behind me, with my backhoe. It is being pulled by tracks, with a smaller engine that would save on fuel. In this configuration if I wanted to load the dump trailer faster then what I could with the backhoe, I could unhook off the trailer and load it with the front bucket of the Dingo...like down at my gravel pit or something.
But if I was operating it as a log trailer, the tracked machine would go through mud and snow, yet have the weight of the wood off the ground so I could move bigger loads of wood, not to mention keeping my logs clean and out of the mud. That is important when sawing logs on your own sawmill. More than likely, the Dingo has plenty of hydraulics too, so mounting hydraulic motors on the log trailer wheels, I could put tracks around the trailers twin bogie wheels and have a (4) tracked, articulated tractor that was small. Talk about a machine that could go anywhere!
As far as farming goes, a person could have the same thing, but have a 3 point hitch that was set onto the log trailer. Again it would be a (4) tracked machine that was articulated. The tractive effort to size would be amazing, so it could not only tow wider tillage equipment, it could go through mud, and not have compaction issues.
If a engine was mounted on the back of the log trailer, a person could have a pto, so the machine could power a flail mower, rototiller, bushog, winch, etc. Once again, it would be a (4) tracked, articulated machine with a low center of gravity.
It would really be an amazing tractor with a lot of capability.
