They claim their designs can allow simultaneous communication of many signals over the same paths, and that a single node in an electronic chip can be allowed to directly communicate to a huge number of other nodes, rather than the very limited fanout of normal current-based gate elements.  They envision massive meshes of processors for parallel computing where each processor can signal all the others at once, all on one chip.  And power consumption is extemely low since electron current is not the means of transmission.
