The reality is that customers buy multiple off-the-shelf routers and 
expect them to work without intervention.  In the IPv6 world that means PD 
needs to work automatically and recursively among the chained routers. 
Depending on how these devices are nested, and how they do PD, the poor 
router at the end of a long chain may not have a whole lot of /64s to play 
with :)
