The anisotropic kagomé antiferromagnet is discussed as a possible candidate for glassiness in the absence of disorder. Numerical studies support the conjecture that this system is not a conventional magnetic system, and we include a discussion of the relevant experimental system SrCr 8-xGa 4+xO 19.
