I cannot recommend strongly enough to find something more suitable for touring. Your carbon road bike is designed for speed, not loads. It would be fine for supported tours, but I think you'll discover a number of problems when going selfsupported, not the least of which will be comfort. Having ridden carbon road bikes and chromoly tourers for nearly two decades, my opinion is that the carbon doesn't come close to the comfort of a tourer over the long haul.
IF you decide to use your carbon, then I don't think you will have much choice other than using a trailer to carry your gear. Aside from what others have mentioned about not having attachment points for a rack,your chain stays are probably not long enough to permit a rack and panniers and still have adequate heel clearance.

The most surprising thing I've read in this thread is that although I've ridden thousands of self supported miles in Europe, Canada and the USA, I'm apparently not a serious tourist since none of my tours have been over ten days. Damn this impediment of having to work to make a living to support my cycling habit (oh, and my family, too).
