Repeating still says you need two hands to use the reload level, that makes the crossbow repeating, to load each round. But it also says it holds 5 rounds, and takes a full round to reload. So IMO as DM i would allow one hand to fire and load the next round as a free action with some feat or special Repeating Light Crossbow, because there is a whole round to reload one crossbow, so maybe two rounds to reload two?
But it would be a very neat class to dual wield light repeating crossbows.
