Re: IPv6 end user addressing

Tim,

    Hence the "might".  I worry when people start throwing around terms 
like routing in the home that they don't understand the complexities of 
balancing the massive CPE installed base, technical features, end user 
support, ease of installation & managemenet, and (perhaps most 
importantly) the economics of mass adoption.  This one of the choices 
that made DSL deployments more complex and expensive than DOCSIS cable 
deployments which in turn caused the CEO of AT&T to say their entire DSL 
network is obsolete.
