I didn't see the article but suspect the person you're referring to is the
Norwegian rallycrosser, Martin Schanche.  He has designed an interesting
diff assembly/transmission that sounds very much like what you describe above.

Since this is, first and foremost, a street car, I'm not willing to modify
the firewall and I'm certainly not willing to pop for a new gearbox so the
limit as to how far I can push the engine back is about 4", maybe a little
less.  More than this would require far too much work and increase the
complexity of my project immeasurably.

FWIW, for my now-aborted racecar project, I did design a poor-man's version
of this diff/tranny assembly using a pair of motorcycle sprockets and a
chain that ran between them.  I'm sure there would have been a considerable
power loss in the process but the price was right!  :^)
