We present results on the transport properties of Pb/I/Pb junctions, where I is either a-Ge or a-InO film. At helium temperatures, such structures sustain non-dissipative currents and exhibit systematic sub-gap I-V modulation. The data are consistent with the existence of a Josephson-coupling mechanism involving quantum mechanical coherent diffusion within the Anderson-insulating barrier.
