puwaha, if a computer or device is purpose built to transmit data over the powerlines, yes, it can do that. But to claim that a generic PC from a run of the mill manufacturer has this built in as a backdoor is utter stupid.

By the way, I initially thought your back and forth with the other guy would keep this thread alive and may be generate some traffic, but if the thread is full of his nonsense on topics not even on a tangent, it would actually hurt us. Just ignore him. I think plenty have understood who represents what in this thread and community.
