I don't know much of carp anymore, but I guess the question is all about
how you plan to have the ARP advertisements. I think there's the need to
"gratuitously" advertise at the event of failover all of the addresses that
are shared. I think it's possible to script up such advertisements in a
user script, but I guess you'd rather have carp handle this since that is
what it's whole reason for being is?

I apologize for outright guessing on a public forum but it's interesting to
me and I'd like to move the discussion along.
