Ethernet thru Electricity
This sounds like a really nice concept, since electricity pretty much exists in most places. Avoids the hassles of cable or telephone lines.
Of course it will be interesting to see how the telephone industry and/or the cable industry responds!
This also reminds me of the Power over Ethernet concept that Cisco pioneered last year - wonder how that is doing.
These are truly creative inventions - almost like the safety pin. Unfortunately for them - there is a lot of "investment" which would go bad if these new products succeed!
