> IPv6 either works, or doesn't Oh, you sweet summer child! :) IPv6 “just works” only if you completely control the routing stack end-to-end. Once end user equipment and hosts are introduced into the network all bets are off. In a mobile network, where the carrier controls what user terminals are allowed on the network, it is at least nominally possible to achieve “just works” status. So, in the real world, forcing IPv6 would result in IPv6 being supported only in a particular configuration used in a particular way. Everybody will be told to go pound sand and no effort will be made to keep IPv6 working or prevent breakage.
