I have this funny idea about a waveguide interconnect, where MIMO radios address each other inside the manifold. You could get pretty decent bus width through e.g QAM and with beam steering probably simultaneous data links. Of course it could be made to look cool as hell, complex microwave plumbing with integrated heatsink replacing a plain old mainboard. :)
