Dave, just looked at your project website and see that you will be using a 36 spoke rear wheel, thats good. I'd consider finding an inexpensive 36er for the front as well, just one thing to not have to deal with on a trip if you are indeed using the 24 spoker shown in the vid.
Do realize these suggestions arent just to be contradictory, but come from experience. Here in Canada, one can find a reasonably priced 36 spoke wheel for maybe $100 or something, and once you take into account busting spokes, having a wheel go out of true, some repair costs etc, time lost...using a low spoke wheel for a fully loaded trip does not seem prudent (you will be carrying a dslr camera, perhaps extra lenses, laptop, maybe a tripod--all extra stuff I never carried when touring--so you may have at least 10lbs more than a non doc making trip)
cheers
