Well, how do I specify which interface to bind that multicast address to? I 
see the `bindnetaddr' directive in openais.conf man page. The cman man page 
tells me that the parameter from the <clusternodes> section will overwrite. 
Now, I haven't been able to find any reference as to the syntax of the 
clusternodes directive.

Also, according to the openais.conf man page, the bindnetaddr directive is a 
subdirective of the interface directive, which in itself a subdirective of the 
totem directive. So I'm wondering if it goes something like what follows:

<cluster>
  <totem>
    <interface>
      <bindnetaddr/>
    </interface>
  </totem>
</cluster>

Can't, in this setup.

Though, is it not at all possible to use multiple multicast addresses to bind 
to on different interfaces? Heartbeat, for instance, allows it.
