It occurs to me that this will only work for the asterisk that starts
up on the machine owning the virtual IP, so asterisk can't be started
up on the other machine with bindaddr on the virtual IP, since that is
not at that time a local IP address.

I guess it would be ok if Asterisk is only started (or restarted) after
the node has taken ownership of the virtual IP.

Cheers
