I don't think the resistive impedance would be a problem, I am sure there is a lot more copper in coax than in each pair of cat5, so simple volt drop would not be an issue. I think the capacitance might be the problem rounding off the signals, but I don't know enough about the physics to know the answer. I am sure it would work over a "short" distance but not over a "long" distance. The question is what are short and long in this context? I am not sure that the ethernet over coax point is valid as I assume the drivers in such an interface would be designed to drive coax. > > Keep us informed, please. Will do.
