Jan isn't using Moab, he's using maui. Moab costs money and offers
more features (like hierarchical fairshare), maui is free.

The fairshare in maui is not hierarchical.  As Gabe notes, you can use 'accounts' to correspond to projects or experiments, but it's still a flat rather than hierarchical share.  I guess you could readily take a logical hierarchical set of shares and convert them to a flat set for the 'leaves' but you would not get the same sort of fairshare between peer nodes in the hierarchy that you would with a 'proper' hierarchical fairshare model.
