According to RC1, you could use a "later version of this Licence similar 
in spirit".

We don't know what would be in the hypothetical ODbL 1.1, but I don't 
know of any licenses that would allow you to downgrade to a previous 
version (if a new license is released to fix problems with the old one, 
that option would kind of defeat the purpose of the release).

As I read RC1, they'll have to honor request for access to the database 
made to them while they were using it publicly, but that aside they can 
stop using the derived database at any time.
