Non-portable is non-portable.  Historically, a sane renumbering window 
is provided.  According to some stories, enforcement of renumbering 
windows has occasionally taken place by re-use of to-be-revoked space,
or its reannouncement to peers in smaller chunks. 

Of course, the new provider should be able to vet the space, see the
'non-portable' note and tell the customer about multioming-vs-moving,
their renumbering guides, contact NAC, etc.  It would be an 
irresponsible provider that would announce another provider's NON-
portable spacewithout the customer clearly multihoming and without
clearance from the originating provider.

Portable space is available from the registry. That is their recourse.
