It should already be possible to do that, although not automatically based on looking at your own IP.. Anyway, non-director servers could simply have the passdb return proxy=y host=director-servers, where director-servers expands to a round-robin list of director IPs (Dovecot uses the first one).

I guess it would be possible to do this automatically if passdb lookup returns proxy=y but no host (means director isn't enabled), but if director_servers is non-empty one of the IPs would be randomly chosen. A little kludgy though..
