Indeed,
Pitlock does make them for Nexus/Alfine in addition to Rohloff.
See page six of their 2011 price list.
They're not listed on
Peter White's Pitlock page (although I'm certain he'd special-order them), but they are available at
Urban Bike Tech. Even says "for Shimano Nexus and Alfine hubs".
Note that due to their larger size, they can't be keyed-alike to other Pitlocks.
