  We propose a hierarchy of spin liquids with spin S, which are generated via a
Schwinger boson projection from 2S (Abelian) chiral spin liquids with S=1/2. We
argue that the P and T invariant liquids we construct for integer spin S
support SU(2) level k=S non-Abelian statistics. We conjecture that these spin
liquids serve as paradigms for antiferromagnets which are disordered through
mobile charge carriers.
