You say "complexity" like it's a difficult or bad thing, it's only a couple of multiplex chains and a couple of sprockets no different to what can be found in millions of Mitsubishi and Toyota 4WD's.
If you have a moment I always like to hear options ....
The complexity is not in the design but in term of unneeded hardware. Also the multiplexing chain drives are either 1:1 ratios or gearing down, not gearing up using parts designed for the exact opposite purpose. Yes it would work but you have other options.
If you read from about half way down on page one through two Kiwi build and I both purposed ideas as far as taking east west type AWD trans axles and reorienting the rear output forward. The CRV gear box I cited sell for around $500 and an adapter plate can be made for very cheap.

nuttin for nuttin but i remember chain drive cars that ran a chain to each wheel... now that gets complex. there was even one a ridiculously huge airplane engine in one but i lost the link in a system crash. not always the safest system, been blamed for a few deaths over the years. a few semi forgotten historical notes, The 1907 Thomas Flyer that won the New York to Paris race in 1908 was chain drive, the Marmon Wasp, winner of the first Indy 500 was a chain drive, AP Macks (not meant for road service, specifically built for the Boulder Dam project, also chain drive) were rated at 7 1/2 tons....
ah yes, here it is in its TWENTY SEVEN LITER
glory
http://en.wikipedia.org/wiki/Babs_(Land_speed_record_car)I never said that it would not work but the key thing to consider in all of these applications is that the chain driven cars you cited are all geared down with chains, not up. Gearing up you have to be concerned about ripping the teeth off the smaller gear because again you are effectively quadrupling the torque applied to it is designed to handle. Smaller gears are good for rpm, not torque.
