filtering /48 is going to be necessary

well... we actually intend to just announce /64's and smaller as well.

i don't see the problem with that.

just get routers with enough memory...

i'm rather for a "specification" of a minimum supported route-size (let's 
say something along the lines of 64GB in each border router, it's 2012 
after all ;) than for putting limits on the prefix sized announced so "old 
junk" can still stay connected to the internet.

let's say, there is 6 billion people in the world.. if they all have 1 
route table entry (average ;) i see no technical limitations on anything 
produced AFTER 2008 actually.

stop buying crap without sufficient ram, or just scrap it and get new 
stuff. (which you're going to have to do to efficiently route ipv6 
-anyway- at some point, as your old stuff, simply doesn't even 
loadbalance trunked ethernet ports properly (layer 3 based) ;)

we can't limit the expansion of the internet, and the independance of it's 
users, just because some people refuse to part from their cisco 7200 vxr.
