Why can I not get "Dueling Banjos" out of my head right now?

Following up the news that the ITU has approved PHY specs for the ITU-T G.9960 (formerly known as the G.hn work), the IEEE (and HomePlug/Intellon in particular) are touting their own success in establishing a single powerline specification. Are we there yet? We'll see - I've tapped some contacts at DS2 to see if they have some comment.
