We describe neutron scattering, NMR relaxation, and thermal transport properties of Z(2) spin liquids in two dimensions. Comparison to recent experiments on the spin S=1/2 triangular lattice antiferromagnet in kappa-(ET)(2)Cu-2(CN)(3) shows that this compound may realize a Z(2) spin liquid. We argue that the topological vison excitations dominate thermal transport, and that recent thermal conductivity experiments by M. Yamashita et al. have observed the vison gap.
