Braze-ons for a rack can be a killer. You can still mount it, but you'll need special hardware for it. I don't see braze-ons for mounting a rack on the Sequoia, either, though. I could just be missing them in the rear, but the fork definitely doesn't have them; also, a carbon fork, while light, might not be the best idea if you plan on making it a high-miler. (Also, the Sequoia definitely doesn't have clearance for fenders... that alone would end the plan for me).
What exactly do you mean by light touring? This term can encompass a lot, but if you let us know what exactly you plan on doing, maybe we can give better advice.
