almost all ip traffic is unintentional. "i want my mtv. money for nothin' and the chicks are free." < from a friend in a big broadband provider > when the average consumer (real) broadband connection becomes v6 capable, about 40% of the traffic is instantly ipv6, thank you netflix, facebook, netflix, google, netflix, and netflix. the brick wall is 'smart' tee vees etc, which do not speak v6, and will have a five+ year lifetime. randy
