Hmm. Originally I implemented it to be similar to the host
configuration, but from the implementation we don't _actually_ need it
as we select the key from the entire key store.
Having it is just a nice way of avoiding having to have a daemon
configuration.
So if you insist we can drop it for the initial implementation.

Hannes
