Yes, in this case, I think this is the best approach. Subclass
ServerManagedPolicy, and on getting a NOT_LICENSED response from the Market
licensing service, query your own server to see if the user is authorized to
bypass the license check. You'll probably want to sign the response from
your server as well, just to make sure it's not being spoofed.
