I am considering adding a network retrieval interface that can be updated/extended. I will try to update with more details when I have them, the current thinking is to have something like this

class KeyFetchingInterface
{
public:
  void
  fetchKeyFromNetwork(const shared_ptr<KeyRequest>& keyRequest,
                      const shared_ptr<ValidationState>& state, (?) accessToValidatorCaches,
                      const Continuation& continue);
};

I see the following use cases for such interfaces:

• basic certificate retrieval (same as currently hard-coded in the validator)
• direct fetch retrieval extension (for certificate only; for all certificate---the latter requires custom data in the ValidatorState)
• key bundle retrieval
• NDNS lookup

Some, if not all, retrival mechanism may need to get combined.
