Re: [time-nuts] Timing on Ethernet

Ah, but what if one used the tunnel itself as a waveguide, and propagated an RF signal down it? Would it then reliably arrive at all the points, with a known delay? Since the tunnels are probably at least ten meters wide and tall, that's a pretty low frequency, which is easy to generate, and
