Ah, like on my old Volvo 340 ;-) They were fun, all that weight at the back (the diff and gearbox were bolted together under the rear floor) gave it excellent balance. Bit of a shame all that 50/50 weight distribution was only pushed along by a 1.4 Renault engine then, I guess.

Have you ever seen the Jaguar IRS setup? It's more like a twin-wishbone suspension *but the driveshaft is the upper link!* It's in compression and stops the hub tilting out, and the rear brakes are inboard to reduce weight even further.
