For that last run - I'd be _very_ concerned about differences in electrical potential frying stuff.

  In the realm of things that shouldn't have worked, I remember my brother in the early-mid 90s strung a telephone-grade wire around a house to directly connect two computers via their serial ports for serial-line IP (SLIP). His best result was using one pair to connect send/receive lines like a null-modem. With XOFF/XON inband flow control and no grounding, he increased the serial port rates beyond what the modems of the day would achieve, and it worked. Our guess was that above a certain rate, it acted more like an AC transmission line and less like ground-referenced levels.

  That's not a real concern, ethernet is galvanically isolated by design. If the cable was shielded and/or foiled you might have a problem, but it almost certainly wasn't.
