Michael,

update speed and reliability of the mapping function are not just needed
for access network mobility.  Its also needed for provider fail-over.

Access network operators want to be able to switch providers quickly
when one goes down.  This is one of the main goals for multi-homing.

Fast provider fail-over requires a very agile mapping function, however.
 To me, it is not clear how either a pull or a push model, or a
trade-off between the two, can support this in a scalable manner.
