From the Sheldon Brown article I posted above:
""Adjustable" means that the hubs use conventional threaded axles, so you can increase the OLD spacing by removing the locknuts and adding spacer washers.
If you add equal thicknesses to both sides, the chainline is unaffected, since it's measured from the middle outward.
If you add more spacers to one side, you can change the chainline, but if you do this with a double-sided hub, you will render it unusable on one side or the other, since you'll be increasing the chainline on one side while decreasing it on the other."
