Check this baby out! It's down near the bottom of the page.

Here's the description.....
BMR carbon fiber driveshafts provide a variety of benefits for your '05 Mustang. The overcomplicated factory two-piece shaft weighs an unbelievable 42.3 lbs. as compared to our 20.7lb. one-piece carbon fiber replacement. This rotational weight reduction alone is responsible for gains of 15+ rear wheel horsepower. Additionally the benefits of carbon fiber can be felt and heard in reduced driveline harmonics and vibration. Carbon fiber absorbs these harmonics much more efficiently without the long term fatique associated with steel or aluminum. The factory driveshaft is rated at an estimated 450-500rwhp while we rate our carbon fiber shaft up to 1000+ rwhp.
BMR's carbon fiber driveshaft comes with a new billet 4340 pinion yoke and a billet 7075 front flange both using heavy duty 1350 series u-joints. The carbon used in these shafts has two distinct wind angles to provide the most unparalleled torsional rigidity(45 degree wind angle) without sacrificing linear strength(15 degree wind angle). Shipped complete with new pinion nut, u-bolts and instructions. NOTE: Rear pinion flange requires professional installation.

Very true about the cost.
I guess this is what you buy if you actually have money left over after buying a CAI, Tuner, Gears, Pulleys, Rims, Stripes, Springs, Control Arms, Sway bars, shifters, x-pipes, headers and stereo equipment............
I sure wish money grew on trees..

Don't forget, that is rotating mass, so a reducing of 20lbs. is quite a bit. Should help the engine rev a lot quicker as well.
Still not sure if it is worth that price though, especially since it will require professional installation.

169Stang just bought one and is getting it installed currently, he had some problems with the factory carrier bearing after several hard launches. I love the idea of this mod but right now it seems out of reach for me. Most likely the cars getting this one will be factory or corporate funded/sponsored race cars. 
Doesn't change the fact that I want one though.

That is the sexist thing I have ever seen. All kidding aside that is so cool and I agree if it was like $600 it would be great but $1100 is a little pricy. Though I could get the install for free.

I will be getting it installed this Thursday. Dyno pull before and after as well. The professional installation is due to the fact that installing a new rear yolk requires setting the pinion gear just like installing a new set of gears. The trick is to measure the current pinion depth, installing the new yolk and setting the pinion depth to where it was before. I don't want to deal with this for one, second, I want it done right. You really need the right tools for doing so and I currently don't have them.
I don't know about any corporate sponsors though.
I was talking to some different people about this and carbon fiber is very expensive as is, let alone a driveshaft. I initially looked into an aluminum one and they are roughly $600-700 for just that shaft. Then you have the yolks left, roughly $200. So you are looking anywhere from $800-$900 for aluminum. I'm not one for buying something due to being cheaper. I look more for quality and try not to have to do any redo's. I'm not saying that the aluminum one from JPC isn't quality. I know it is! Justin has one in his car now. If it wasn't great, he wouldn't be using it. I talked with a couple people and the concensus was that the carbon fiber would be a bit better. I'll spend a little extra for better. Until there are quite a few making them and the current companies can get their production costs down, it's going to be a bit more expensive. It's possible that if I lined up 5 or 10 takers, I could get the price down a bit. I really have no idea. I'd have to inquire. Maybe a poll or thread with a group buy. If a single person is interested, I'll make the calls.
