I'm guessing a bunch of filtering goes on with the actual power, but beyond that I have no clue. I guess part of this is I was wondering if it is feasible to develop a frontend to stick a USRP in to a wall socket. Then, due to the horrible channels you mention, I think it makes for an interesting/feasible 3 month project to get communication through to power line with those channels. Even measurement on what those channels are like would be interesting, and I know whatever might come out of this would really open up the ability for the academic community to directly research power line networks.
