The Future of Flying?

WorldChanging caught my eye with this post: The Future of Flying is Batwing:

Airline passengers of the future will have to do without window seats and fly in "batwing" aircraft as a result of aviation industry proposals to tackle greenhouse gas emissions from flights.

Seated 40-across in the body of the wing? Sounds cool to me. Seems like we've been flying the same 7x7-like contraptions for way too long. I hope I live long enough to fly in such a craft.
