At the rate I'm going it'll be next fall before I actually get to try my dynamo setup. Of all things, the spokes and nipples I ordered were held up because the nipples were on BACKORDER. GMAFB. Just send me a substitute. And then the light I chose, the new B&M CYO Premium, is on backorder everywhere except Peter White, but even he may be on backorder as his page is not connected to his inventory.

Anyway, to answer a few of the questions above: Cost? A lot more than a battery light. I'm $150 into the wheel and I haven't order the light. Weight? Pretty heavy hub, heavier than the batteries would be. Brightness? TBD. It should be almost as bright at 80 lux as a ~400 lumen light, but with a directed beam. Wires? Not really an issue, they only run from the hub to fork crown mounted light. Friction? There will be some, but everyone says you don't notice it. Theft? I never leave my bike outside anyway. Standlight? Yes, but it doesn't last forever.
