This memory jump has occured more than once. I remember 4 and 8 meg
routers. 16 meg boxen were deamed large enough when they were created.
The leap to 64 is just another step in the process.

As an aside, is anyone else besides Sprint behind this /18
model? I know that Sean is a big proponent but I have heard
no other public comment on this. (well there was one, which
indicated that the community had reached consenses on this point,
which is why I ask.)
