crm_mon shouldn't really display expected votes for heartbeat
clusters... they're not used in any way when heartbeat is in use.
expected votes is only relevant for ver: 0 of the pacemaker/corosync plugin.
in the future pacemaker will obtain quorum information directly from
corosync, but at the time (openais 0.80) we didn't have that available
to us.

I dont think so, the ccm doesn't expose that information.
