My own opinion is that whatever transfer/reclamation policy we implement, 
it will simply smooth out and mitigate some of the negative effects of an 
abrupt transition to IPv6.  To put it another way, it makes it possible to 
extend the dual-stack phase of the v4-v6 transition so that we aren't 
forcing some organizations to turn off v4 before everyone else has turned 
on v6.

The precise timing of the various phases will depend on a lot of factors, 
but I don't foresee sticking with v4 for another decade as even remotely 
viable.
