Btw, it's not about whether an admin wants a specific node number or not.
It's about which layer is coming up with the node number. I completely agree
with Andrew, that fundamentally, pacemaker just wants to get node numbers
from openais (validity checking aside). Of course we're here because that
doesn't *quite* work for some consumers which we all care about :)

Maybe he meant "different schemes of coming up with otherwise valid
nodeids"? For example, maybe the ip munging code is slightly different
between plugins, etc. Anyway, I think Steve makes a better point about this
in a later e-mail.
