The term "overkill" comes to mind.  How many name servers does one  
actually need (anycast or not), particularly given the concept of  
caching?

While router hardware will undoubtedly be more powerful, the question  
of whether or not BGP will be able to converge with everybody and  
their great aunt having PI space is still open. Then there is the  
question of whether or not people will be happy with the O(10) ISPs  
capable of affording the hardware/power/cooling of the future DFZ  
routers (have you priced top-end routers recently?).

This proposal seems a bit on the extreme side to me.
