> Is there an opto coupler (opto isolator?) suitable for lan cables? - if so - that would allow you to do this.
You making this suggestion at all means you haven't read the writeup, or you didn't understand the issues. Read the text, and if it's still unclear why "opto-isolator" is a moot point, ask again and I'll explain. Before you ask aloud, ask yourself what you want to achieve.
