Good.

Yes it is. Make each director have a real "external" IP, RIPext, and a
real "internal" IP, RIPint.
You then have an "external" VIP for services (or more than one), VIPext,
and an "internal" VIP *which is the default gateway address for the
realservers*, VIPint. This completely decouples the service addresses
from the management addresses.
You then make ldirectord failover both VIPext and VIPint at the same
time.
How you configure it to do that I'll leave as an exercise :)
