aads renumbering rumor and implications

[Randy Bush <randy () psg com>]

i am told that aads seems to be planning to renumber, seemingly as there is
some service charge for the address space they do not wish to pay.  please
correct/confirm.

should this be true and  a real issue,

  o will folk be happy renumbering at larger exchanges?

  o does anyone see why the exchange address space needs to be globally
    routable?
