500k is imho no different than 250k 128k 100k. Some devices are going to 
fall off the applecart. some folks will engage in heroic measures to 
police their fib size and the world will move on. million route and 2 
million route fib platforms abound. if we cross the million mark in 10 
years we're fine. if we cross it in 2 (which doesn't seem likely) then 
we have a problem. the v6 table imho is the one to watch.
