AT&T - your "powerline" broadband provider?

I wonder how many times a day the CEO of the AT&T pounds his head on his desk and curses Mike Armstrong. As you know, a few years ago AT&T owned a cellular network, a long distance business, and most importantly a huge cable tv business. After splitting up the company, AT&T is now trying to get back into the businesses it just left. After the acquisition of AT&T wireless by Cingular, AT&T will start selling wireless service under their name again borrowing from the Sprint Network. To recover the broadband piece of the puzzle, it appears that AT&T is going after selling broadband over powerlines.
