Yes, certainly anyone who has v6 already deployed would be  
inconvenienced.  However, I'm not willing to sacrifice the  
architecture of the net to grandfather those few folks in forever.   
If they want to play, they should renumber.

Again, we can start in a specific prefix so that we can have  
interoperability and have a rolling migration.  However, everyone  
*should* play the same game, eventually.

Of course.  However, no pain, no gain....
