I would classify this as a failure of imagination. If RRG is indeed  
aiming at 10 to 20 years in the future, I would be quite astonished if  
an underlying assumption is that the way the Internet is today is the  
way it will be one to two decades in the future, just bigger.

My assumption is that as people become more and more dependent on  
Internet connectivity for their day-to-day lives, the less interested  
they will be in periodic outages.  When the myriad devices in your  
house depend on being connected to the Internet and you have a wide  
variety of layer 2 technologies over which to connect (e.g., WiMax,  
FTTH, Cable, DSL, and their successors), I fully expect most domestic  
subscribers to be multihomed.  Actually, I expect it to be worse than  
that -- I can very easily imagine multi-homed PANs connected to  
multiple providers via cell phone-as-router-equivalents.

As such, in my opinion, a design that does not anticipate (or at least  
cannot scale with) massive multihoming would be a waste of time.

FWIW.
