Paul,

I think that's unnecessarily one dimensional.  The needs of business  
to be connected in a reliable fashion are above and beyond being for  
or against CIDR.  Rather, they are the requirements for the routing  
architecture that the Internet has yet to fulfill.

Single homing is bad simply from a reliability standpoint, and the  
only true technological impediment to everyone multi-homing is cost  
and the routing architecture.  Consider the ability of the average  
consumer to make use of WiFi to provide mutual backup connectivity to  
his neighbors with alternate last mile providers.  As the cost goes  
to zero, everyone will want to multi-home.
