there is a new draft on MAP deployment in the works. should be out any day now.

it is certainly simpler if you have some available IPv4 address space to start with.
e.g. with a /14 of IPv4 space, you'll get 16 million subs for a sharing ratio of 64. or a /16 with a sharing ratio of 256 .

> What would the deployment process be for an address exhausted network of 10 million subs with 10% annual growth be? 

if you have zero IPv4 addresses left to play with. you can convert a subscriber at a time. then for every subscriber converted, you'd get sharing-ratio-1 IPv4 addresses reclaimed, that you can do the same with.
