Ethernet over power cables

What does everyone think about making a homebrew Ethernet over Mains plug adapter?

If you have to ask (on instructables) then you probably shouldn't try. Mains is dangerous, ethernet over mains is hard.
This is one of them projects that would be best just to shell out the 50 bucks than to try and build one yourself. I can think of a few problems that can go wrong.

I think it would be pretty complicated to do "homebrew"... There's lots of "magic" that goes on trying to transmit at that sort of speed over "regular wire"; recall that the original 10Mbps ethernet used bright yellow coax as thick as your thumb...
