If you want your client application to load-balance although the locally

actually return all available IPs to the client and let it chose one
(i.e. implement the random algorithm in your application). That way,
'gethostbyname' etc. could return all entries as well.
Yes, this would be an option. I rejected this approach because it breaks
the api.
Yes, that's why it hasn't been changed, yet. Maybe we could add an
additional function that returns all cached addresses from the local
cache array... This might be sped up by passing in the ip_addr_t
pointer form the 'found' callback, which could be used to calculate back
the entry index.
