Let's face it - the current v6 assignment rules are to solve a 1990s set of problems. A /64 isn't needed now that we have DHCP(v6). Setting the idea in people's heads that a /64 IS going to be their own statically is insane and will blow out provider's own routing tables more than is rational. (Think of the processing overhead of all the DSL/Cable customers going up and down). This is going to be far more of an issue and drive network design than a minor blow out in the v6 routing table.And before anyone says "there are 281474976710656 /48s!", just remember your history. I was not there when v4 was spec'ed out, but I bet when someone said "four-point-two BILLION addresses", someone else said "no $@#%'ing way we will EVER use THAT many...."
As Neil Finn of Split Enz fame once wrote: History never repeats, I tell myself before I go to sleep. Followed on the same album by a song called "My Mistake".
