[arin-discuss] Multihomeping proof for IP space request

I have a client that will be multihoming with us and a new provider as 
soon as the DS3's are installed.  They will be dropping their current 
provider.
Can they go ahead and request their own IP space and somehow show proof 
that they will be multi-homed in 60 days or so?
The client wants to go ahead and start renumbering as they are afraid 
the current provider will abandon them when they get the news that their 
contract will not be renewed.
