That range alone is 25 bits of routing, equivalent to routing all the way 
down to /25s in the IPv4 world. But I don't see how you could route some 
/48s without having software to route all /48s and that is hugemongous. 
And then times 4 for 128 bits. But, I'm not a routing engine guy, so I'm 
probably missing something ...
