FWD 'bents aren't uncommon. It solves the usual chainline problems by exchanging them for some even more headache-inducing ones (depending on gearing), but can make a substantial weight saving.
The flevobike concept is particularly well suited to FWD, as the steering doesn't cause the wheel to foul the chain.
The trippy bit is how the hell you ride the thing in the first place. I believe that once you've cracked that particular bit of voodoo, you can happily steer with your feet.
