Bengrahamman,
I think you'll find that most knowledgeable practitioners in the field, including consultants, writers and pundits, won't stick their necks out for BPL the way they once may have done for DSL, when it was at a similar placement on the curve, or even FTTH.
Maybe the reason for this is because BPL has shown too little, a bit too late, and to repeat a major shortcoming I cited earlier, it doesn't have the headroom (higher-speed potential needed to compete with the telcos and cable operators) to bring it to the next level, even if it did perform interference free. Another reason why it is a tough nut to crack in North America, as opposed to the European examples often cited, has to do with the methods and distances used in the clustering of homes around neighborhood substations and feeders, which may be quite suitable for electic power distribution purposes, but less so for communications.
If the power line communications vendors can't get 300 kb/s to 1 Mb/s right without introducing interference, then I'm not holding out too much hope for them to get 30 Mb/s right, especially if they are portending to be the "only" necessary wire in the home, at least not in the foreeseeable future.
