Good to see replies still trickling in for this thread. I wired the dynamo up quite a while back and ended up routing the cable along the bottom of the main frame tube. I used plain clear packing tape to hold it in place with the intent of using a much higher quality 3M clear packing tape. Since then I've changed my mind and decided to use some Shimano Di2 wire loom to hold the wires in place where they run along the main frame tube. I received the Di2 stuff a couple weeks ago but haven't had time to put it on yet. I'll post back with my impressions regarding that option.
