Every business that wants to multihome and can afford it already does. v6 
isn't going to change that. v6 will allow more aggregation and a routing 
table closer in size to the number of AS's, which is a significant 
reduction. It should also reduce the problem of route churn and 
non-convergence. Whether everyone will play nicely and make it work is a 
different story.
