Cyril, I'm not quite sure I follow (I'm not an electrical person, my only knowledge is based from what we learn in Cisco certification), but does that mean that the ground potential isn't an issue because of the cabling requirements for 802.3?

Hi, yes the ethernet standard calls and uses transformers as isolation, specifically to avoid ground loops, if you open any switch or NIC you will find a small black epoxied box that contains this coupling tranformer.

munkieboy I agree, wireless is probably the go, ubnt is a very cost effective 5GHz option.

The cabling will still attract a lightning strike - depending upon the surrounding areas and the local weather patterns.

However, you can place an ethernet lightning surge protector at each end of the cable as it goes into the house. Also most cheap asian brand hubs and routers are designed to resist a small surge quite well to prevent returns to the manufacturer.

Telephone lines are just as bad, and they are not just connected to telephones anymore. I dont even think they use lightning protectors on telephone lines at all.
