I still don't see the need for different behaviour. In both cases, what you need is a "slow" get_key() (it's not performance critical anyway) that communicates with GPU and returns the actual correct key for that very index.

For status reports, you could just as well report it as "abcd***" where the '*' show parts that are generated on GPU but since you need to implement the proper function anyway, this is not a very interesting option.
