[Linux-cluster] Higher Grained Definition of IP Address Assignments?

[Dustin Henry Offutt]

Appreciate the info, but indeed what we need is HA.

I need to perhaps request if a cluster developer would be willing to add 
a new configuration item to the IP xtag within the cluster.conf 
configuration that would allow one to specify IP an IP label to apply 
the IP resource to.

This /could/ be done via a cluster resource script - but then we'd lose 
the ability to have the cluster software monitor the link and relocate 
the service should the link be lost.
